Why Do Cats Roll Over Into Their Backs But Not Let You Touch Their Bellies?
It’s common knowledge dogs love to have their tummies rubbed when they freely lay down before you and roll onto their backs. But, if you’re also familiar with cats, you know that when they roll onto their backs with their bellies exposed, rubbing the belly will most likely result in bleeding. So why do they do this? advertisement An expression of trust Cat behaviorists will likely answer that it’s a sign of trust when cats roll over and expose their bellies. That is true, indeed. But is it also a request to rub their bellies? The fact that your cat

What Is Manx Syndrome?
Manx Syndrome is a collective term that describes a group of genetic conditions commonly found in Manx cats. These conditions are linked to the breed’s characteristic taillessness, caused by a genetic mutation known as sacrococcygeal dysgenesis, which affects the tail’s development. Unfortunately, this genetic anomaly can also impact the development of the spinal cord, leading to several health problems. advertisement Common Conditions Associated with Manx Syndrome Here’s a look at some of the primary conditions that fall under Manx Syndrome: 1. Spina Bifida Spina bifida is a developmental condition where the vertebral arch (the bones of the spine) fail to fuse during fetal development, leaving a cleft along the spine. This condition is present at birth and can result in the spinal cord becoming exposed. The symptoms may vary from mild to severe and include: Weak hind limbs: The cat may limp or hop. Urinary incontinence: This can lead to secondary urinary tract infections. Constipation: This can progress to a condition called megacolon over time. Partial hind limb paralysis: Difficulty with movement or a lack of control over the hind legs. Seizures: Occasional seizures might occur due to the abnormal development of the spinal cord. 2. Hydromyelia Hydromyelia is a condition where the central canal of the spinal cord becomes enlarged and fills with cerebrospinal fluid. This can cause pain and increase the risk of infections. It can also contribute to neurological symptoms. 3. Syringomyelia This condition involves the formation of cysts or cavities within the spinal cord. Cats with syringomyelia may experience pain, numbness (pins and needles sensation), and balance issues. 4. Myelodysplasia This refers to abnormal bone marrow development and can lead to conditions like anemia (low red blood cell count) and weakened immunity (due to low white blood cell count), as the bone marrow is responsible for producing blood cells. 5. Spinal Malformations Manx cats may also have malformed or misaligned vertebrae, shortened spinal bones, or abnormal sacral and pelvic bones, all of which contribute to mobility issues and discomfort. Diagnosing Manx Syndrome Diagnosing Manx Syndrome often starts with a detailed history of the cat’s health and behavior, particularly focusing on any issues related to movement or the spine. Due to the breed’s well-known association with spinal issues, a vet will usually suspect Manx Syndrome fairly quickly when symptoms appear. Additional tests, such as X-rays, MRIs, or myelography (a procedure where a contrast medium is injected into the spine for clearer imaging), may be necessary to get a more detailed view of the condition affecting the cat. How Is Manx Syndrome Treated? Unfortunately, there is no cure for Manx Syndrome. However, supportive care can help manage symptoms and improve the cat’s quality of life. This is called palliative care and may include: Pain relief: Medications to ease any discomfort from spinal issues. Supportive care: Fluid therapy, oxygen supplementation, and nursing care if the cat needs hospitalization. Inducing urination: In cases of urinary incontinence, the bladder may need to be manually expressed or treated with a urinary catheter.
Hyperthyroidism in Cats and Treatment Options
Hyperthyroidism is a common condition in older cats, typically resulting in noticeable weight loss and changes in behavior. While several treatment options are available, including surgery to remove the affected thyroid tissue, be sure to weigh the risks and benefits. What Is Hyperthyroidism in Cats? Hyperthyroidism occurs when the thyroid gland produces excessive thyroid hormone, which controls the body’s metabolism. The thyroid gland is located near the cat’s neck and comprises two parts on either side of the windpipe. advertisement Most cases of hyperthyroidism in cats are caused by benign (non-cancerous) growths within the thyroid gland, which result in the overproduction of hormones. This condition is most common in cats over eight years old, affecting about 10% of cats in this age group. Thankfully, aggressive thyroid cancers are rare, accounting for less than 5% of cases. Symptoms of Hyperthyroidism in Cats The overproduction of thyroid hormone affects various systems in the body, such as the heart, kidneys, skin, and muscles. Cats with hyperthyroidism may show the following symptoms: Weight loss: Despite an increased appetite, affected cats often lose weight. Increased appetite: Cats may eat more than usual but still lose weight. Behavioral changes: Cats might become more vocal, hyperactive, and sometimes more aggressive. Goitre: An enlarged thyroid gland can be seen or felt in the neck area. Increased heart rate: Cats may develop an abnormally fast heart rate. Hyperthyroidism can also contribute to other health issues, including heart enlargement (cardiomyopathy), high blood pressure, inflammatory bowel disease, and bladder infections. In some cases, it may also mask underlying kidney disease, which can worsen once the thyroid condition is treated. How Is Hyperthyroidism Diagnosed? Diagnosis typically starts with a blood test to measure thyroid hormone levels. If the thyroid levels are elevated above the normal range, hyperthyroidism is confirmed. In some cases, particularly in the early stages, the condition may not be easily diagnosed with a single blood test. In these cases, additional tests may be necessary, including tests for kidney function and urine analysis to determine the most appropriate course of treatment. Treatment Options for Hyperthyroidism There are four main treatment options for hyperthyroidism in cats: medication, diet, radioactive iodine therapy, and surgery. Each option has its advantages and limitations. 1. Anti-Thyroid Medication Anti-thyroid medication is often the first treatment option. It works by blocking the production of thyroid hormones. This treatment is available in tablet form, liquid, or as a gel applied to the skin inside the cat’s ears. The downside of medication is that it does not cure the condition, so the cat will need to be treated for life with regular blood tests to monitor hormone levels. Common side effects of medication include loss of appetite, vomiting, and skin reactions. While affordable in the short term, the cost can accumulate over time. 2. Iodine-Restricted Diet For cats that do not tolerate medication, an iodine-restricted diet may be an option. This food limits the production of thyroid hormones and requires the cat to eat only the special food with
Should Cats Be Kept Indoors?
For many cat owners, the debate over whether to allow their feline companions outdoors is a common one. While the idea of cats freely roaming outdoors may seem appealing, it’s important to weigh the risks and benefits to determine what’s best for your pet. From natural behavior expression to safety concerns, this article explores both sides of the discussion to answer the question; should cats be kept indoors? advertisement Why Outdoor Time Is Beneficial for Cats Cats are naturally curious creatures, and their behavior thrives in environments that mimic their instincts. Here are several reasons why having access to the outdoors can benefit your cat: 1. Expressing Natural Behaviors Outdoor spaces offer cats the freedom to express behaviors like stalking, hunting, as well as territorial marking—activities that are hard to replicate indoors. A garden or yard filled with leaves, insects, and climbing structures gives them the opportunity to engage in these natural activities. 2. Physical Exercise The outdoors provides ample space for cats to run, jump, and chase. With more room to move, they can engage in high-energy activities that keep them physically fit. Additionally, this will help prevent obesity. A cat can climb trees, pounce on moving objects, and explore different environments, enhancing their agility and fitness. 3. Mental Stimulation Outdoor environments stimulate all of a cat’s senses. The constantly changing surroundings keep them alert and engaged, from the sound of birds to the sight of passing cars or people. This stimulation helps prevent boredom and reduces the likelihood of stress-related behaviors. 4. A Safe Escape Sometimes, the environment indoors can become stressful for cats due to visitors, loud noises, or changes in the household. In these instances, outdoor time offers cats an escape to a quieter, calmer space, where they can find solitude in a garden or simply watch the world from a safe vantage point. The Risks of Outdoor Access While outdoor time can be beneficial, there are also several significant risks involved. Here are some of the dangers that your cat may face outside: 1. Traffic and Vehicles Road accidents are one of the most common dangers for outdoor cats. Even in quieter, more remote areas, cats are at risk of being hit by vehicles, especially young, unneutered males who may wander further from home. Limiting outdoor access to daylight hours as well as ensuring your cat is neutered can help mitigate this risk. 2. Conflict with Other Cats Cats are territorial animals, and encounters with other cats can lead to aggression, fights, as well as emotional distress. Even if they aren’t directly fighting, the presence of rival cats can cause stress. It’s essential to manage your cat’s interactions with other neighborhood cats to prevent behavioral problems. 3. Loss and Theft Cats often disappear without a trace. Whether they get lost, injured, or are stolen, the risks of your cat going missing are real. Microchipping and neutering your cat can help ensure they are returned safely if lost or stolen. 4. Poisoning Outdoor cats are at
Scottish Fold Cats: Adorable or Harmful?
The Scottish Fold cat is undoubtedly one of the most charming and distinctive breeds. They are known for their iconic forward-folded ears, which give them an owl-like appearance. These cats are undeniably cute and have been made famous by social media, with celebrities like Taylor Swift and Ed Sheeran often sharing pictures of their beloved Scottish Folds. However, there’s a lesser-known side to the breed that raises concerns. While these cats may be adored for their appearance, their distinctive features come at a cost. Let’s explore the origins of the Scottish Fold and the health issues that can plague this breed. advertisement The Origins of the Scottish Fold As the name suggests, the Scottish Fold originated in Scotland. In the 1960s, a white barn cat named Susie was discovered in Perthshire with a unique genetic mutation. This mutation caused her ears to fold. This unusual trait was linked to a cartilage defect, causing the ears to fold downward rather than stand up, as in most cats. When Susie gave birth to kittens, many had the same folded ears. Seeing an opportunity to capitalize on this charming look, Susie’s owner began breeding her with British Shorthairs and other local cats. The result was the Scottish Fold breed, which soon gained popularity, particularly in the UK and the US. The Hidden Problem Behind the Folded Ears While the folded ears of Scottish Folds are undeniably cute, the genetic mutation that causes them has serious health consequences. The same defect that affects the ear’s cartilage also impacts other parts of the body, leading to Osteochondrodysplasia. This incurable disease causes painful, swollen joints and affects cats as early as 7 weeks old. Scottish Folds are prone to malformations in their forelimbs, hindlimbs, spine, and tail. This often results in stiff, painful, or fused joints. Unfortunately, these issues aren’t just limited to a small percentage of Scottish Folds – all cats of this breed will experience these problems at some point. The joint pain caused by this condition severely impacts the cat’s mobility. It can cause lameness and an abnormal gait, making it difficult for the cat to perform everyday behaviors such as walking, running, jumping, and grooming. A Conundrum for Pet Lovers While the Scottish Fold has an excellent temperament and a unique, lovable personality, there is growing concern about breeding animals with known health issues for their appearance. Veterinary professionals, including organizations like International Cat Care and The British Veterinary Association, agree that intentionally breeding cats with a genetic mutation that causes lifelong pain and discomfort is unethical. Prospective pet owners should consider the long-term health and happiness of their future pets rather than being swayed solely by appearance. While Scottish Folds are undoubtedly adorable, their quality of life may be compromised. advertisement What to Consider When Choosing a Cat If you’re thinking about bringing a new kitty into your home, here are some key tips to keep in mind: Avoid breeds with extreme or “designer” features. While these cats may look cute,
Chin Acne in Cats: Causes, Symptoms, and Treatment
Chin acne in cats is a skin condition that affects the hair follicles on a cat’s chin, forming blackheads (comedones), pimples (pustules), and even more significant, boil-like sores. This condition is thought to be caused by the overproduction of keratin. Keratin is a protein found in the skin’s outer layers, which can clog hair follicles. When these follicles become blocked, inflammation and infection can occur, resulting in the characteristic symptoms of chin acne. advertisement What Causes Chin Acne in Cats? While the exact cause of chin acne remains unclear, several factors are believed to contribute to its development. It is thought that abnormal follicular keratinization may be linked to an overproduction of sebum (the natural oils produced by the skin), which could indicate seborrheic diseases. Other potential triggers include stress, allergies, viral infections, or immunosuppression, but none have been definitively proven to cause feline acne. Interestingly, there may also be a connection between using plastic food and water bowls and the development of chin acne. The scratches and irregular surfaces found in plastic dishes can trap bacteria, increasing the likelihood of infections that could lead to acne. What Are the Symptoms? The most common sign of chin acne is a dirty or greasy-looking chin, with the formation of blackheads and infected follicles. These lesions typically appear on the chin, lower lip, and sometimes the upper lip. The area may also become swollen, red, and inflamed. In more severe cases, the lesions may harden, become crusty, and be painful to the touch, especially if they progress to furunculosis (large, boil-like sores). How is it Diagnosed? Chin acne is generally diagnosed based on clinical symptoms and the cat’s medical history. Additional tests such as skin cultures, blood tests, skin cytology (to check for bacteria or yeast), or culture sensitivity tests may be used. In rare cases, biopsies or skin scrapings are recommended to rule out other conditions, such as cancer or immune-mediated diseases. Dental X-rays are sometimes conducted to ensure that an infected tooth root does not mimic chin acne’s appearance. How Is Chin Acne Treated? Treatment usually begins with improving the cat’s hygiene. The affected area is typically cleaned with benzoyl peroxide facial preparations or anti-seborrheic shampoos to flush out the hair follicles. Topical antibiotic ointments like mupirocin (Muricin®) are highly effective for many cats. However, clindamycin gels or liquid preparations (Antirobe®, Cleocin®, ClinDrops®) are also commonly used. Omega-3 fatty acid supplements are often recommended to support skin health, as they can help reduce inflammation. In more severe or persistent cases, oral antibiotics, corticosteroids (to reduce inflammation), or even isotretinoin (the human acne drug Accutane®) may be prescribed. Another simple solution that may help improve chin acne in some cats is to replace plastic food and water bowls. They can be replaced with non-porous, smooth-surfaced alternatives, such as glass or stainless steel. Its also important to ensure these dishes are washed daily. advertisement What is the Prognosis for Cats with Chin Acne? Most cats with chin acne respond well to treatment,
Can Adopting a Cat Reduce Your Risk of Heart Disease?
Cats are more than just adorable companions—they could also reduce your risk of heart disease. A recent study published in the Second National Health and Nutrition Examination Study Mortality Follow-up Study suggests that adopting a cat may help lower the risk of fatal cardiovascular diseases, including heart attacks and strokes. advertisement The Surprising Link Between Cats and Heart Health We’ve long known that pets, in general, can reduce stress and provide emotional support. However, this new study digs deeper into the potential health benefits of having a cat. Researchers set out to determine if there was a relationship between cat ownership and the risk of fatal cardiovascular diseases. The study examined over 4,400 people over 20 years, including their history of cat ownership, and found some compelling results. According to the study, those who had previously owned cats showed a significantly lower risk of dying from a myocardial infarction (MI), also known as a heart attack. Specifically, the relative risk (RR) of death due to MI was 0.63 in participants who had previously owned a cat, meaning they were 37% less likely to die from a heart attack than those without cats in their lives. Cats: The Natural Stress Reliever So, what could be behind these surprising findings? Cats are certainly capable of being a calming presence, and interacting and petting them can lower blood pressure and reduce anxiety. These effects may be why cat ownership is linked to a lower risk of cardiovascular events. The idea that pet owners, particularly cats, can lower stress isn’t new. Previous research has shown that pet ownership can lead to lower levels of cortisol, the hormone associated with stress, and higher levels of oxytocin, the bonding hormone. This hormonal balance could be the key element in managing the long-term effects of stress, which is a known contributor to heart disease. Not Just Heart Attacks: Cats Could Help Prevent Strokes Too The study also found a trend toward decreased risk of death due to cardiovascular diseases (CVD) in those who had owned cats. The relative risk for CVD-related death in those with a history of cat ownership was 0.74. While the results were not as strong for stroke-related deaths, the data still suggests that having a cat might contribute to overall heart health. Could Cat Ownership Be a Heart Disease Prevention Strategy? The implications of this study are significant. If owning a cat can lower the risk of heart attacks and strokes, it could offer an additional, simple strategy for reducing the risk of cardiovascular diseases—particularly in individuals who are already at higher risk due to factors like high blood pressure, high cholesterol, or diabetes. The best part? No special medications or interventions are required—simply welcome a feline companion into your home. However, it’s important to note that while the study shows a link between cat ownership and lower cardiovascular risk, it doesn’t prove direct causation. More research is needed to understand the biological mechanisms behind these findings fully. advertisement Conclusion: Time to Adopt
Do Cats Have Nine Lives? Unpacking the Myth
Cats are often known for their agility and near-miraculous ability to avoid danger, earning them the age-old reputation of having “nine lives.” This saying has been passed down through generations, likely because cats seem to cheat death. But where did this myth come from, and do cats possess supernatural powers? advertisement The Origins of the Nine Lives Myth The phrase “a cat has nine lives” is rooted in mythology and folklore. The saying likely traces back to Ancient Egypt, where cats were revered and associated with several deities, including the sun god, Atum-Ra. Atum-Ra was said to have given birth to eight other gods, making the number nine significant in their culture. Some believe this connection to the number nine is why cats were thought to possess nine lives. Interestingly, the myth spread as cats expanded across the globe along ancient trade routes. As the Egyptians worshiped cats, their mythologies about these agile creatures also traveled far and wide. Why the Number Nine? The number nine carries special significance in many ancient traditions. For the Ancient Greeks, nine represented a magical number associated with gods and the cosmos. In Hinduism, nine is seen as a divine number, while in Chinese culture, it is linked with the powerful symbol of the dragon. This universal reverence for the number nine may have influenced the widespread belief that cats had nine lives. It’s possible that the myth survived because of its symbolic power and the idea that cats were worthy of such an elevated status. The number of lives cats have is believed to vary in different cultures. For example, in Arabic culture, cats have six lives; in Spanish-speaking countries, they’re often said to have seven. The number seven is considered magical, associated with luck, and usually thought to enhance the “lucky” nature of cats. advertisement Cats and Their Remarkable Agility One of the main reasons cats are believed to have multiple lives is their exceptional ability to survive dangerous situations. Take, for example, the viral video of a cat surviving a fall from a football stadium roof in Miami. After clinging to the edge with one arm, the cat fell around 30 feet. But instead of suffering fatal injuries, it was rescued and unharmed. Indeed, cats are known for their “righting reflex,” which enables them to twist their bodies mid-air and land on their feet during falls. This ability, combined with their flexible bones and light body structure, allows them to survive falls from impressive heights—often to the astonishment of humans. The “Escape Artist” Nature of Cats Cats’ survival ability isn’t just about physical traits but also about their instincts. Cats are incredibly independent and have evolved to be escape artists. Whether in the wild or as pets, they can often survive difficult situations on their own. If a cat becomes lost, it can usually find food, shelter, and safety, even if it has to fend for itself for a while. Moreover, cats are fiercely independent creatures. Unlike dogs, who often forgive
What Is Kitten Season? How to Help Your Local Shelters During This Busy Time
Have you ever heard of kitten season? Kitten season is when animal shelters experience a surge in kittens caused by increased cat births. While it sounds like a simple season, it can overwhelm shelters, strain resources, and lead to overcrowding. advertisement What Is Kitten Season? Kitten season is when outdoor cats mate and give birth, typically starting in early spring and continuing through late fall. While cats can give birth at any time of the year, warmer weather encourages more mating and births. This leads to a significant increase in kittens born, especially those found outside. As a result, shelters see more strays and abandoned kittens, placing a heavy burden on their resources and available space. When Do Cats Have Kittens? Female cats can become pregnant as early as four months of age and remain fertile for most of their lives, typically between 7 and 8 years. Cats enter heat cycles every 2-3 weeks to produce multiple litters from multiple mates yearly without spaying. The gestation period for a cat is typically 63-65 days or around two months. So, while the peak of kitten season occurs in the warmer months, cats can have kittens at any time if not spayed. advertisement How You Can Help During Kitten Season There are several ways you can help alleviate the strain on shelters during kitten season and reduce the number of homeless kittens: 1. Spay or Neuter Your Cats One of the most effective ways to help control the population of stray cats is by ensuring that your cats are spayed or neutered. If you’ve recently adopted a kitten or cat, schedule a spay or neuter appointment with a vet. Additionally, a veterinarian can provide vaccines and checkups to ensure your kitten’s health. 2. Helping Stray Kittens If you find kittens outside during kitten season, assess their condition. If the kittens are healthy, friendly, and over two months old, consider helping care for them until they are ready for adoption. In the meantime, contact local shelters to see if they offer trap, neuter, and return (TNR) programs. These programs help control the stray cat population by spaying and neutering feral cats before they are returned to their outdoor homes. 3. Foster Kittens Shelters often need foster families to care for kittens during kitten season. Fostering is a great way to support your local shelter without making a long-term commitment. Most shelters provide all the necessary supplies, including food, bedding, and toys. By fostering, you can offer a safe and comfortable environment for kittens to grow before they are ready for adoption. 4. Adopt a Kitten Adopting a kitten can help ease the burden on shelters if you’re ready for a new feline friend. Consider adopting one or two kittens from your local shelter. This gives a loving home to a kitten and opens up space for other cats in need. 5. Volunteer Shelters often experience a greater need for volunteers during kitten season. Volunteering can involve helping with cleaning, socializing kittens, or assisting
How Cat Bodies Maintain Homeostasis
Cats seem to balance their health and well-being effortlessly while still being silly little guys, squeezing into boxes and seeking the one sliver of sunlight to nap in. This balance your cat is striking is thanks to homeostasis, which allows them to regulate essential functions like body temperature, fluid balance, and pH levels to keep everything running smoothly. advertisement Temperature Regulation One key way your cat maintains homeostasis is through temperature regulation. Cats are not like warm-blooded humans. Instead, they are “thermal conformers,” meaning they adjust their body temperature to match their environment. This means cats have several strategies for staying comfortable in hot and cold temperatures. Cooling Down: Cats groom themselves to stay cool on hot days. When they lick their fur, saliva spreads and evaporates, helping cool their skin. Similar to humans, cats can also sweat through their paw pads. Warming Up: Cats curl into a tight ball to conserve heat when it’s cold. They can also raise the hairs on their bodies to trap air between the fur, acting as insulation against the chill. Fluid and Electrolyte Balance Like humans, cats must stay hydrated to keep their bodies functioning correctly. Drinking Water: Cats instinctively drink water throughout the day to stay hydrated. The kidneys also balance electrolytes by filtering excess ions, such as sodium or potassium, from the bloodstream. Osmoreceptors: Cats have specialized cells called osmoreceptors that detect changes in salt concentration. These cells trigger thirst or adjust urine production to keep the body’s water and salt levels in check. pH Regulation Cats’ overall health requires maintaining a stable pH level. Their normal blood pH is slightly alkaline, around 7.4. If the pH drops below 7.35 or rises above 7.45, it can lead to serious health issues. Kidneys: The kidneys help regulate pH by filtering out excess hydrogen ions (which are acidic) and reabsorbing bicarbonate ions to buffer acids in the bloodstream. Respiratory System: Cats can also regulate their pH through their breathing. By exhaling carbon dioxide, they can reduce acidity in the blood, which helps maintain the proper pH balance. Respiratory and Cardiovascular Systems A cat’s heart and lungs work together to deliver oxygen throughout the body and remove carbon dioxide. This dynamic system helps maintain homeostasis by regulating oxygen levels and blood flow. Respiratory System: The lungs take in oxygen, which is absorbed into the bloodstream and carried throughout the body. At the same time, carbon dioxide is removed from the blood through exhalation. Cardiovascular System: The heart pumps oxygenated blood to all organs and tissues while regulating blood pressure and heart rate to ensure everything gets the oxygen and nutrients it needs. advertisement Behavioral Adaptations Your cat also has behavioral strategies that help maintain homeostasis. Their instincts help them stay healthy by responding to environmental changes or internal cues. Self-Grooming: Cats are known for their meticulous grooming habits. This behavior keeps their fur clean and helps regulate their body temperature by spreading saliva and removing excess fur. Hunting Behavior: Cats’ instincts to hunt and
The Finnish “Salmiak” Coat Color Discovery
A recent discovery from Finland has uncovered a completely new coat pattern and genetic variation. The Finnish domestic cat population has been found to have cats with a striking white and colored hair pattern, dubbed “salmiak. ” This new phenotype, which resembles a tuxedo cat with a unique white gradation in its coat, is caused by a previously unknown genetic variant associated with a large deletion in the KIT gene. advertisement What is the “Salmiak” Cat Coat? The salmiak-colored cat is named after the Finnish term for “salty licorice” due to the cat’s distinctive color pattern. This pattern is most noticeable in solid black cats. However, can appear in other color backgrounds, such as brown tabby, tortoiseshell, and blue (dilution). The salmiak pattern features a mixture of white and color-gradated fur that starts with a solid color at the base of the hair, fading to white at the tips. The characteristic coloration is present from birth and remains stable throughout the cat’s life. Although the salmiak pattern was first observed in 2007 in the Petäjävesi region of Finland, it has only recently been studied. A genetic cause has similarly only recently been studied. Genetic Cause of the Salmiak Phenotype The study of the salmiak cats led researchers to investigate the genetic background of this coat coloration. DNA samples were collected from five salmiak-colored cats. The team then used genetic sequencing methods to search for the gene responsible for the distinctive pattern. Interestingly, traditional tests for white coat patterns, which are commonly associated with the KIT gene, did not show the usual variants linked to full white or white spotting patterns. This led the researchers to focus on a different part of the genome. Upon closer inspection of the genome, researchers found a sizeable 95-kb deletion. This was found in a region located approximately 65 kb downstream of the KIT gene. This is involved in developing melanocytes (cells responsible for pigment production). This deletion was associated with the salmiak phenotype. This is suggested to be the genetic cause of this unique coat pattern. The newly identified variant has been named “wsal” for “w salmiak”. This is to distinguish it from other known white coat-related variants in cats. The KIT Gene and Its Role in Coat Color The KIT gene significantly affects coat color patterns across various species, including cats. Known mutations in the KIT gene can lead to variations in the amount and distribution of melanocytes. These variations can cause different patterns of white coat color in cats. For example, cats’ well-known white coat patterns are typically caused by inserting a feline endogenous retrovirus (FERV-1) in the KIT gene. This causes full white coloration or white spots on the coat. The salmiak pattern, however, does not show these known insertions, which is why the discovery of the 95-kb deletion downstream of the KIT gene is significant. Broader Implications for Cat Genetics The discovery of the wsal allele is an important addition to cat genetics. It highlights the complexity and diversity of
