Why Does My Cat Roll on Its Back and Bite?

You look down to see your cat roll over on his back and stick his belly out. He looks so cute and that belly so irresistible. Unfortunately, when you go to pet him, he bites your hand.

Why does my cat roll on its back and bite? Cats usually have sensitive bellies and don’t like people to pet that part of them. This explains why they bite when rolling around if you pet them on the belly. As they roll around, they almost look like they want a belly rub. Instead, pet them on the head or cheeks.

If you’d like to learn more about how to keep from getting bitten when your cat rolls on its back, keep reading because we will look at the best ways to handle a cat.

Why Do Cats Roll on Their Backs?

To begin, let’s look at why cats roll on their backs. When a cat does this, it depends on the context. For example, cats that roll in the dirt may be doing this for a few reasons like dust bathing. They might be cooling off, playing, itching themselves or getting rid of parasites.

Cats also roll on their back when they feel happy or to catch your attention. This shows friendship and trust because they usually expose their belly when doing this, which makes them vulnerable.

Know Your Cat

Generally speaking, we can assume that your cat bit you while rolling on its back because you rubbed its belly. We call this the bear trap. It looks like an invitation, but if you rub that belly, you have signed up for bite marks on your hand.

Not all cats dislike having their belly rubbed but most do. You have to learn the unique traits of your cat to know what upsets him and what doesn’t.

Provided you’re familiar with the cat, they usually warn you before they bite. They rarely use full force right away unless you continue to try rubbing their belly. What the cat is saying is, “I don’t like this. Please stop.”

Cats vs Dogs: Different Behavior

The trouble enters when people think of cats like the same as dogs. Dogs behave differently, and they rarely bite when rolling on their back unless provoked. You can rub their belly and some seek it out even.

Cats respond differently to this because they’re both a predator and an animal of prey. When you rub their belly, their instinct usually warns them against you doing that.

Many of the cat’s vital organs sit less than a millimeter underneath the fur in this area. Injury to any of them can lead to death. For that reason, when he rolls on his back and bites, he’s protecting himself.

What if My Cat Bit Me, and I Didn’t Pet His Belly?

We have reserved an answer just for you. We assumed before that your cat bit you because you pet his belly, but what if you didn’t? What if he rolled around and bit you for no reason? Looking at cat behavior, you have multiple reasons for why this may have happened.

Think of what you did before he bit you.

Were you petting him? You may have hit a sensitive spot that he didn’t want to have pet, which resulted biting. The best places to pet a cat include the ears, under the chin and cheeks. The tummy, back and base of the tail could all be sensitive points, depending on the cat.

Let’s say that you weren’t petting him. Your cat may be saying that he wants to be on his own. Give him some space. You may have messed up the greeting as well. The distance for the greeting can be tricky because each cat has their own preference for how far away you should be when greeting them.

Expert Tip: Whenever petting a cat, take it slow, especially with an unfamiliar cat. Let the cat decide how things will progress.

I talked about how to approach a cat who has done a social roll here.

Play Fighting? Really…?

In some cases, your cat may roll on its back and play-bite you because he wants to play. You can tell by the lack of seriousness that the cat does this. Playful cats may also have dilated pupils.

The one thing about play fighting is that your cat may be play fighting, but you could still have a hard time doing this without receiving scratches or pain from bites. Say, “Ouch!” loudly to let him know that it hurt. This teaches your cat how much force to use while playing.

In general, it’s probably better not to play with your cat this way. If you continue to play with him like this, he will think of grabbing your arm and biting as a game. If left unchecked, your cat may eventually bite or scratch whenever a hand comes near, thinking of it as a game—not good!

Cats Don’t Know the Difference

Cats can rarely tell the difference between playtime and not playtime. They won’t know when it’s okay to bite playfully and when not to, so never encourage your cat to bite.

Instead, we would recommend the MeoHui Interactive Cat Feather Toys to redirect his aggression from your hand over to a feather toy. This makes play with him more fun while giving him the exercise that he needs to stay healthy.

Kitten vs Adult Cats: Rolls on Back and Bites

Kittens are especially playful, and they will likely do this for the reasons outlined above—in the sacred name of play. However, kitten play bites may hurt more because they haven’t learned to measure their bites.

They learn this through roughhousing with their littermates. One lets out a yelp when another kitten gets too rough.

Don’t Encourage Bad Habits

For that reason, when your kitten rolls on its back and wants to play, you may want to have the feather toy handy so that you can play without hurting your hand or encouraging bad habits.

The other danger from encouraging play biting is that he may not do this with just you. He may bite a child or a dinner guest. As you can imagine, that could be very problematic.

An adult cat is less likely to do this because he wants to play, which is where kittens and adult cats differ.

How Do You Respond to a Cat Like This?

First, make sure that you’re not rubbing his belly. That’s the likely reason that your cat bites when doing this. You may try to pet his belly from the side to see if he responds better. Some cats will allow that.

If that doesn’t help, you can simply ignore your cat altogether when he does this, which prevents him from biting you—especially if you find it unpleasant, that’s your best option.


Your cat will roll on its back as a gesture of trust. You never see a cat expose his belly unless he trusts you. On a cat, the belly is the most vulnerable part. That also explains why he bites your hand when you go to rub his belly. Humans think he wants his belly rubbed, but he doesn’t. His instincts kick in to defend himself.

Not all cats dislike having their belly rubbed, but most go into defensive mode. You have to gauge your own cat. In fact, it’s well known that every cat has certain places on the body that he doesn’t want touched.
