Why Do Cats Purr And Knead

Top reasons cats knead

There are many theories about why cats knead. Kittens, for instance, learn to knead when nursing from their mothers at young ages. They also like to mark their territories. By kneading they are rubbing and activating the scent glands in their paws to possibly mark their territory. They can also knead to stretch their muscles as a form of relaxation.

Also, they can purr, stretch, and knead the air while lying on their side in the stretched-out position. Usually, they do this to tell male cats that they can approach for a possible mating opportunity.

According to Wikipedia “Multiple theories exist that explain why cats knead. Kneading may have an origin going back to cats’ wild ancestors who had to tread down grass or foliage to make a temporary nest in which to rest.”

So What does it mean when your cat is purring or kneading

So your cat’s behavior is purr-fectly normal. Most domestic cats have these strange behaviors the minute they are born. It is an instinct natural to them. However, we all know that if they start Kneading on your lap it can be quite painful.

Since they do have tiny little razors as nails. Use a pillow or blanket underneath them. And more importantly, do not scold them for their natural behavior. They really cannot help it.

Not all cats purr, as in the video large cats like lions and jaguars roar rather than a purr. Also sometimes the cat has a very low frequency not allowing us to hear them. You may feel rumbling or them trying to purr but another sound may come out.

This is perfectly normal as well. However, if you notice that your cat is purring constant or for long periods of time. I would consult with your vet to make sure there are no underlying disorders. Sometimes their vocal cords do not develop as soon as other cats.
