Do Humans Struggle to Speak Cat?

Most cat parents have experienced it: a cat rolls onto their back, the fluffy belly is exposed, and the human hand reaches in on instinct. Moments later, teeth, claws, and a very offended feline. What looks like an invitation is often a perfectly clear feline “no thanks.”

Recent research suggests the problem isn’t that cats are confusing; it’s that humans are surprisingly bad at reading them.

Humans vs. Cat Body Language: The Results Aren’t Great

A study of 368 adults examined how well people could interpret cat emotions from short video clips of human–cat interactions. The results were far from reassuring:

• When cats showed obvious distress, hissing, spitting, tense or aggressive postures, 23.3% of people still misread them.
• When cats displayed subtle signs of discomfort, such as slight stiffness or facial tension, accuracy dropped to just 48.7%, basically a coin toss.

Even more concerning, recognizing distress did not always change how participants said they would behave:

• Among people who correctly identified a cat as stressed or annoyed, nearly 20% still said they would interact with the cat instead of backing off.
• For cats showing subtle negative signals, that number increased to 44%.

In other words, even when humans understand that a cat is not okay, many still choose to push the interaction.

Why Misreading Cats Can Be Dangerous

Misinterpreting or ignoring feline warning signs is not just impolite; it can be physically dangerous for humans and stressful for cats.

Cat Bites: Tiny Teeth, Serious Damage

• 75% of infection-causing mammalian bites come from cats.
• Roughly 30% of cat bites become infected, which can lead to:
  • Deep abscesses
  • Bone infections
  • Septic arthritis
  • In severe cases, long-term disability or life-threatening illness

Cat teeth are narrow and sharp, creating deep puncture wounds that often close quickly at the surface while bacteria multiply inside.

Cat Scratches: Not Harmless Either

• Scratches can cause corneal injuries if they reach the eye.
• They can transmit cat scratch disease (bartonellosis), which causes chronic lymph node swelling and has been associated with longer-term health concerns.
• Scratches contaminated with saliva can, in rare cases, transmit rabies.

Hands and arms are the most common targets. About half of all cat-related injuries occur there, often during play or petting sessions, where humans miss the moment the cat’s comfort level changes.

The Belly Rub Trap

One of the most common misunderstandings between humans and cats involves the exposed belly.

When a cat rolls onto their back, it can mean:

• Trust
• Relaxation
• A desire to interact, but not necessarily through belly touching

For many cats, the belly is a highly vulnerable and easily overstimulated area. Touching it can quickly trigger a defensive reaction.

In the study, when participants watched videos of cats showing subtle signs of discomfort, 42% still said they would rub the cat’s belly. That is exactly the sort of interaction likely to end in biting, scratching, and frantic bunny kicks from all four paws.

When Education Backfires

To see if education could help people read cats better, researchers created a brief 2.5-minute training video about feline body language and play cues. Half of the participants watched this video; the other half watched a neutral video about general cat care.

The results were mixed:

• For obvious behaviors (clearly happy or clearly upset cats), the training video helped slightly:
  • Accuracy for clear positive signals improved by 1.9 percentage points.
  • Accuracy for clear negative signals improved by 1.4 percentage points.

However, things went in the wrong direction for the behaviors that matter most in everyday life:

• For subtle negative signals, early warning signs that a cat is getting uncomfortable, accuracy dropped by 18.8 percentage points among those who watched the training video.

In other words, after watching a “learn to read cats” video, people felt more confident but actually became worse at spotting the early signs that a cat wanted space.

This combination, high confidence and lower accuracy, is especially risky. It can lead people to believe they “speak cat” while continuing to misunderstand what their cat is trying to say.

Does Experience with Cats Help?

The study also explored whether living or working with cats improves understanding of feline body language.

• Living with cats provided some benefit:
  • Cat owners showed about an 11-point improvement in recognizing negative behaviors overall.
  • However, this did not significantly improve recognition of subtle distress cues.
• Professional experience (veterinary staff, shelter workers, etc.) showed a somewhat stronger effect:
  • Those with vocational cat experience were about 8.1 points better at recognizing subtle negative behaviors.

Even with experience, though, subtle cues remained challenging, underscoring how easy it is for humans to misinterpret early warning signs.

Where It All Goes Wrong: Misreading Emotions

Participants were also asked what specific emotion the cat seemed to be experiencing.

• For obvious negative behavior, most correctly chose something like “frustrated” or “annoyed.”
• For obvious positive behavior, “playful” was selected the majority of the time.

But subtle cues caused confusion:

• For subtle negative behaviors, people often split between “playful” and “frustrated/annoyed.”
• Participants also frequently chose “relaxed” or “happy” for cats that experts identified as showing early signs of stress.

This misunderstanding helps explain why unwanted interactions continue. Humans often truly believe the cat is content or playful, when in reality, the cat is asking quietly for space.

How to Really Respect Cat Boundaries

Fortunately, once people are aware of the issue, they can start making simple changes that improve safety and trust for both cats and humans.

Learn to Spot Subtle “No, Thanks” Signals

Watch for early signs that a cat is reaching their limit:

• Body becoming slightly stiff or tense
• Tail flicking, twitching, or lashing
• Ears rotating outward or flattening, even a little
• Whiskers pulling back or a more tense facial expression
• The cat nudging your hand away or trying to move off

Any of these signals means it is time to pause or stop the interaction.

Rethink Belly Rubs

If a cat rolls onto their back:

• See it as a sign of trust, not a guaranteed invitation for belly touching.
• Offer gentle scratches on the chest, cheeks, or head instead.
• If testing the waters near the belly, move slowly and be ready to stop at the first sign of tension.

For many cats, a simple rule works best: no routine belly rubs.

Don’t Use Hands as Toys

Hands should be for petting, not wrestling.

• Use toys, especially wand toys, for interactive play.
• If a cat starts grabbing or biting hands during petting, gently disengage and redirect to a toy or end the session.

What This Means for Cats, and Their Humans

Most cat bites and scratches happen at home, from cats that know and trust their people. They often occur during play or petting that goes just a little too far, because the human misses or misinterprets the cat’s quieter signals.

This research highlights:

• Humans tend to overestimate their ability to interpret cat body language.
• Subtle signals of discomfort are frequently misunderstood or overlooked.
• Even when distress is recognized, people do not always adjust their behavior.

The encouraging part is that small changes in awareness and behavior can make a big difference. By:

• Watching more carefully
• Giving cats more choice in interactions
• Respecting early signs of discomfort

Humans can create safer, more trusting relationships with their feline companions. The next time a cat’s body stiffens, its tail starts to twitch, or it gently blocks your hand, that is not “random” behavior. It is communication. The kindest response is simple: listen.
