Why does your cats back end quiver when he kneads?

It's a common misconception that a cat's back end quivers when they knead! It's actually their front paws that move in a kneading motion.

Here's why they do it:

* Instinct: Cats knead as a leftover instinct from kittenhood. When they were tiny, kneading helped stimulate their mother's milk flow and also served to mark their territory.

* Comfort: The rhythmic motion of kneading is soothing and comforting for cats. It releases endorphins and helps them relax.

* Stretching: Kneading can also be a way for cats to stretch their muscles and tendons.

* Marking: The scent glands on a cat's paws release pheromones when they knead, which helps them mark their territory.

While it's a natural behavior, it's important to note that some cats can knead with more force than others, which can be painful if they do it on humans or delicate surfaces.

If your cat's kneading is causing you discomfort, you can try redirecting them to a more appropriate surface like a blanket or a scratching post. You can also gently discourage the behavior by saying "no" or redirecting their attention to a toy.
