Why do cats purr?

Cats purr because petting feels nice. They make a soft rumble. It can mean, “More gentle pats.” Cats can purr in a warm lap.

Cats often purr when they feel safe and happy, like when they are curled up on a lap. The soft rumble can help them show, “I like this.” Sometimes cats also purr when they are scared or sore, a bit like how you might hum to feel better.

Cats purr by making tiny parts in their throat move very fast as they breathe in and out. They often do it when they feel safe, happy, or close to someone. Cats may also purr when they are frightened or hurt, because the steady vibration can comfort them. Fun fact: mother cats and kittens purr to each other before kittens can see well.
