Why do cats and kittens purr?

Reasons a cat purrs

Cats purr for different reasons, but the most likely one is a sign they’re feeling happy and content.

Purring is also a cat’s way of keeping calm and feeling safe when they’re unable to escape a situation that makes them fearful. They may purr to soothe themselves when they’re feeling unwell too.

How do cats and kittens purr?

Cats and kittens purr through a process that involves vibrations in their voice box, caused by signals from the brain. As this happens, the muscles tighten and loosen, which is what creates the sound as they breath in and out.

Do cats purr in pain or when sick?

Yes, cats will sometimes purr if they’re sick or in pain. It’s their way of trying to self sooth and feel better.

Why does my cat gently bite me while purring?

Some cats will gently nip their owners when they’re purring. If the purring is an expression of joy, the nip is likely an indication of them being slightly overstimulated.

This can happen when they’re having a lot of fuss and attention and feel a build-up of energy. If you find your cat doing this, it’s best to stop fussing them and allow them a little time to calm down.

You could let your cat remain on your lap while calming down, or you could help them spend some energy by engaging them with one of their toys.

If you need them off your lap and they’re nipping when you try to move them, try throwing one of their toys a few feet away from you – wands or feather toys are great for cats to chase. This could divert their attention and – hopefully – encourage them to move!

Why has my cat stopped purring?

Some cats will naturally purr more, or louder, than others, while some can also be very quiet.

If your cat has stopped purring and they’re usually quite vocal, it could be a sign of stress, change in the environment, illness or discomfort.

It’s important to consider other signs of stress in cats – purring isn’t the only indicator. If you notice any changes in your feline friend that concern you, speak to your vet.
