Aggression in Cats: Petting Induced

Why does my cat bite when I pet them?

Some cats that appear perfectly comfortable resting in a lap can suddenly turn around and bite. Often, there do not seem to be any warning signs. This behavior is sometimes called “don’t pet me” aggression, and it occurs for different reasons in different cats—it is not always clear what drives it.

What appears to happen is that your cat enjoys the interaction for a while, but at some point, the physical sensation of being stroked and scratched is no longer pleasant. Instead of hopping down and walking away, your cat bites. Some cats deliver a light bite that does not even cause a scratch, while others bite hard, causing a puncture wound. Because cat bites easily become infected, petting-induced aggression must be taken seriously.

If your cat tolerates prolonged petting once it has begun but sometimes bites when you first reach toward them, the bite may be related to miscommunication. Cat behavior can be confusing to us and our behavior is probably confusing to our cats. For example, when a cat rubs their cheek on a person’s leg, they may not be requesting petting.  The cat may simply be covering the person with a familiar scent. There are scent glands in a cat’s cheeks that secrete pheromones—chemicals 

Another example of miscommunication occurs when a cat jumps onto a person’s lap. Although many cats enjoy companionship and appreciate the softness and warmth of a lap, they are not necessarily interested in being stroked. For these cats, being petted disrupts their comfort rather than providing a pleasant experience.

Finally, your cat may approach you to request something else, such as play or food. A bite may occur due to frustration if they receive petting instead.

What should I do if my cat bites me?

First, take care of your wound and call your doctor—cat bites can be serious. If the bite does not cause an injury, quietly walk away and give your cat space to relax. 

Do not punish your cat, as this will create fear. Your cat may be trying to communicate discomfort. Do not try to interact until you and your cat are both relaxed. Some cats relax more quickly if they can access a quiet and private room. It can take minutes to hours for some cats to recover.

What could affect my cat’s tolerance for being petted?

If your cat shows unexpected aggressive behavior, bring them to your veterinarian for a thorough examination. Pain can trigger an aggressive response to being touched and should be considered if bites mainly occur when you pet your cat in a specific area of their body.

Your veterinarian will examine your cat’s ears, teeth, and gums for signs of infection or inflammation. When a cat experiences discomfort in a joint, limb, neck, or back, even a slight shift in position, as often happens during petting, can cause pain and trigger a bite. Inflamed skin, as occurs with dermatitis, may increase a cat’s sensitivity to touch. In these cases, being petted can cause discomfort, particularly when it continues for an extended period.

A cat’s emotional state can also affect their tolerance of being petted. Fearful cats often startle easily and may quickly bite if a person reaches toward them unexpectedly, particularly if they have recently encountered something frightening, such as a loud noise or new odor. Cats may bite rather than flee if they perceive that they are cornered.

Is there any way to predict when my cat will bite me?

Any time you pet your cat, watch closely for subtle signs that they are uncomfortable. Notice whether they freeze or move away when you reach toward them with your hand.

When your cat is in your lap, watch for signs of discomfort, whether you have been petting them for a while or are just reaching over to stroke them. Notice whether they pull their ears back, tense their body, or begin to flick their tail. 

If you see any of these signs, stop the interaction immediately. It may help to distract your cat by offering something fun. For example, ask them, “Do you want a treat?” and invite them to leave your lap for a treat.

Your ability to predict your cat’s mood may improve if you keep track of situations in which your cat consistently appears to enjoy being petted. If there are specific times or contexts in which petting is not well tolerated, plan alternative interactions during those times, such as play. Also, learn whether your cat resists being petted on certain areas of their body.

Can this behavior be treated?

There are ways to reduce the likelihood that your cat will bite you. Treatment depends on the specific reason for the behavior. Consult a veterinary behaviorist to determine the physical and behavioral factors that motivate your cat to bite.

To begin, learn your cat’s subtle warning signs. Try to anticipate your cat’s tolerance for petting and keep petting sessions short enough to stop before these signs appear. Communicate with your cat by saying “All done” in a cheerful voice to signal that you are about to stop petting. Practice this cue during short petting sessions—just one or two strokes. Then say, “All done” and stop petting, tossing a treat or toy to reward your cat for remaining calm and tolerant.

Later, if you are petting your cat and notice signs of discomfort, you can say, “All done” and your cat may recognize that you are stopping. Your cat may even recall that after you say, “All done,” a treat usually follows. This may help ease tension.

Over time, with additional training, it may be possible to increase the length and frequency of petting sessions. The first step is to recognize your cat’s threshold. Learn how many strokes are consistently tolerated and always stay below this threshold. The goal in each training session is to stop petting while your cat is calm, then say, “All done,” and reward them with a small, tasty treat.

How can I make interactions with my cat safer?

If you cannot predict either the triggers or your cat’s tolerance for petting, you may need to adjust or eliminate physical interactions with them for safety. For example, when your cat sits close by or on your lap, you may enjoy their company but should not try to pet them. Other cats may tolerate light scratching in certain areas, such as around the neck and chin, but will bite if you attempt to pet them with longer strokes, particularly along the back and sides.

For safety, it can be helpful to use a physical barrier to prevent social interactions at high-risk times. You may confine your cat to a nearby area with a tall baby gate that they cannot climb or jump over, or provide a quiet room with a litter box, food and water, cozy resting places, and some interactive toys. A barrier may also be needed to protect people at higher risk of injury or complications, such as a young child or someone with a weakened immune system in the household.

Are there any other treatment strategies?

• Many cats show calmer behavior in response to pheromones. The Feliway Optimum® diffuser may be a useful addition to treatment. 
• To reduce injuries from scratching, you may use Soft Paws nail caps or trim your cat’s nails.
• Underlying physical and behavioral illnesses should be treated. 
• For cats showing signs of fear, anxiety, or frustration, medication may be helpful.

Will my cat still enjoy interacting with me if I don’t pet them?

Yes. There are many social interactions you and your cat can enjoy. Instead of snuggling, introduce activities such as trick training and playing with wand toys. If your cat is physically fit, try agility activities in your living room or basement. Your cat may enjoy these interactive enrichment opportunities more than they ever enjoyed being petted.
