Why Is My Sweet Kitten Biting Me—and How Do I Stop It?

If you wonder, “Why is my kitten biting me?”—you should know that kitten biting is a natural practice. Kittens explore their world by mouthing objects with (OUCH!) needle-sharp teeth. However, normal exploration and kitten games can turn into a cat biting problem.

Kittens bite for many reasons. If your kitten won’t stop biting, you need to set limits and learn effective methods for training, such as clicker training for kittens. Keep reading to understand the motives behind kitten biting and find out how to put a stop to it—for good.

Why Does My Kitten Keep Biting Me?

To figure out the reasons behind kitten biting, ask yourself what the cat gets out of it. Depending on the kitten’s personality, socialization, age and other factors, there may be several reasons why your kitten is biting.

They’re Exploring

Kittens don’t have hands. They use their mouths (and teeth!) to test everything. Picking things up, biting objects (including your ankles or hands) teaches them how such things act and react. Biting a toy makes it squeak. Biting your ankle makes you squeal and run (fun stuff!). Biting a bee stings back. Everything teaches them a lesson.

They Feel Bad

Kittens may bite if they’re sick. A tender tummy from worms, or a sore paw from that bee sting, means your touch hurts. Kittens bite when they feel pain, stress, or just plain tired and grumpy and don’t want you to mess with them. If you suspect your kitten is biting out of pain, consult your veterinarian immediately.

Stranger Danger

Kittens who are shy or fearful also can bite to make that scary thing—you—back off.

Play Aggression

Kittens start play biting at about 3 weeks of age, and social play reaches its peak between 9 weeks through week 16 and begins to fade thereafter. Momma cat and siblings teach kittens that bites hurt and to pull their punches.

Singleton kittens (kittens without siblings) increase play aggression games around 5 months of age, and the biting can be explosive. These kittens have no other playmates, and so may go from sweet lap snuggles to biting in seconds.

Adopting a pair of kittens allows them “legal” outlets to wear each other out, until they outgrow the behavior by about 9 to 12 months of age. I recommend when possible that you adopt a pair of kittens together, so they teach these lessons naturally. Otherwise, it’s up to us humans to teach kittens to stop biting.


They Need Attention

You may be rewarding the behavior without realizing it. Kittens think it’s a fun game when you squeal and run. When kittens don’t receive enough mental stimulation during the day, even “bad” attention is better than being ignored. Besides enriching your kittens environment and giving them plenty of positive interaction, consider how you are reacting to your kitten’s biting.

How to Stop a Kitten From Biting

You won’t eliminate kitten biting entirely, but you can offer better alternatives to nailing your tender toes, ankles or nose. Punishment that hurts or scares kittens is NEVER acceptable and can make biting worse by turning play-bites into defensive aggression. The key to bite training is four-prong:

    1. Interrupt the inappropriate bites
    2. End positive attention
    3. Offer a better target
    4. Reward good behavior

Interrupt Inappropriate Kitten Biting

Kittens have a very short attention span, so the interruption must happen right as they chomp your ankle or nails or your hand. A very effective way to interrupt a young kitten from biting is to make a percussive “SSSST!” hissing sound that imitates the mother cat. Since a feline hiss means, “Back off, I’m warning you!” this works especially well with young kittens under about 4 months of age.

The second effective bite interruption is a loud and short noise, like a shriek or howl. A short yelp is effective because it explains that biting hurts you. Kittens are smart and learn cause-and-effect very quickly. Kittens who play don’t want to hurt you; they want the games to continue. The short “EEEK!” not only startles and interrupts the biting, it explains what you think of their out-of-control play behavior, too.

This yelping tactic is most effective for older kittens up to 6 or 7 months of age. Please reserve this method for play aggression in kittens 7 months or younger, though. A shriek near a growling or hissing older cat could increase feline aggressive behavior or even prompt an attack.

End Positive Attention

When consequences are pleasant, they increase the chance a behavior will be repeated. It’s cute to allow kittens to play with your fingers when they’re tiny, right? Then they get big and it’s not so cute anymore. Whoops! You’ve taught the kitten it’s fun to target your hands—a hard lesson to un-learn.

People often reward biting without realizing it. Jerking away your hands or dancing around to dodge kitten bites make hands and feet even more alluring, because cats are triggered by movement.

It’s hard to do, I know, but grit your teeth and hold still. If they’re latched on to your hand, instead of pulling away, gently apply pressure into their mouth. That will prompt them to open wide and release your hand. Do this at the same time as you hiss or yelp.

Then stop the games and positive attention. The sequence should be: bite = no games. They’ll learn that any time they bite, the fun stops. The only way for playtime to continue is if they learn to inhibit their bite.

Choose Better Targets and Rewards

Don’t just wonder, “Why is my kitten biting me?” Offer your kitten a “legal” object to bite. Use cat plush toys or a cat feather wand to wear out all that energy. Encourage the kitten to bite and chase the toy (rather than your hands or ankles). Praise them for bunny-kicking the stuffing out of the toy! But if they nail you again, end the game immediately.

During the crazy kitten times, carry a stuffed toy with you to offer as a positive interruption/distraction. When you see Junior Kitten revving up to zoom out and grab your ankle, offer a preemptive toss of the toy and redirect the attack.

In the case of my own cat who arrived when she was about 5 months old, the “hiss” didn’t work on her. The “yelp” interruption was very effective, although at that age, she easily got wound up with play-aggression and sometimes forgot herself. The “bite = no games” cured her of all biting, because she wanted so badly to be with her people.


Kitten biting may be cute in the beginning, but it can become a bigger problem later on by encouraging the behavior. It may take trial and error of different techniques, but in the end you will help your new kitten to learn how to play nice.
