Why Do Cats Scratch People?

Cats scratch people for a few reasons…

  • Illness
  • Self-Defense
  • Accidentally
  • Claws don’t yet retract

The first thing to investigate when your cat scratches you is whether there’s an injury or illness causing pain or sensitivity.

Is this happening only when you touch a certain place on your cat’s body? Or when you pick her up a certain way?

There could be an injury, arthritis, or other problem you can’t see.

It’s worth having your vet do a thorough exam and discuss your observations to discover or rule out medical issues as an underlying cause.

We cats never scratch or hurt people because we’re mean or spiteful… there’s always a reason.

It’s usually as a defense against a threat and can be accompanied by biting… claws and teeth are our only weapons.

Often people don’t realize that something they’re doing is provoking fear and threatening their cat.

Cats give lots of warning signals that you and your children can learn to read and respect their boundaries.

A major part of feline self-defense when faced with a threat is to run away and avoid a fight.

But if the threat doesn’t go away and there’s no choice, any cat will do what it takes to make it go away, even if it’s necessary to inflict major injury or kill it.

This includes both front and back claws… ever stuck your hand in that blender? The kicker move can really get you!

The key is to know what you do that a cat sees as threatening and change your behavior.

Think of the last time your cat scratched you. What were you doing at the time?

Cats usually aren’t inviting you to touch that sensitive area and will defend it.

Overstimulating with too much petting or touching the wrong areas will elicit a swat (or more if you don’t get the hint!).

Accidental scratches are usually from a cat’s claws being too long.

Clipping them regularly helps keep them healthy and reduces these types of scratches.

Other unintentional scratches are when cats do things like jump down from your lap and dig in their back claws for balance and stability.

The cat sees no difference between the chair and your lap and has no idea this will hurt you.

This also happens when a cat is startled, jumps up and launches with claws out from where she was sitting.

Young Kittens

Kittens are born with claws that don’t retract, so they’re not able to sheath them.

It’s like having tiny sharp pins poking into your skin… ouch!

They’re born this way because it helps stimulate their mother’s milk when they knead, helping ensure their survival.

It also helps them grab onto things while learning to balance and climb.

Once kittens are about 4 weeks old, their little paws start being able to retract the claws.

Most people won’t be dealing with this… it’s not an issue by the time they get their kittens.

Are Cat Scratches Dangerous?

Getting scratched by a cat hurts and can be frightening for people.

While they’re nothing to panic about, scratches can get infected, and some diseases like cat scratch fever can be transmitted to humans.

It’s important to wash scratches immediately and watch for any symptoms of infection or fever.

If you have any concerns about a scratch (or bite), contact your doctor right away.

If you’re scratched or bitten by an unfamiliar cat, check with your doctor about the risks and how to handle them.

Detailed information about cat scratch fever symptoms and other diseases is available at “Cat Scratch Disease“.

Sources used on this website are either primary or secondary.

Primary sources are always preferable and have the most reliable information because they’re original and directly referenced.

Scientific abstracts and data are good examples of primary sources.

Secondary sources are weaker because they usually consist of opinions or articles that give no sources of their own.

However, sometimes they refer to primary sources.

When I use secondary sources, most are those with some authority, such as veterinarian or cat behaviorist books and articles.
