Do Cats Have Bones in Their Tails?

A cat's tail is more than just a furry appendange. Even though it's not technically part of the spinal cord, a cat's tail has 19 to 23 vertebrae, about 10 percent of the total number of bones in the animal's body. A labyrinth of muscles, ligaments, and tendons helps the kitty to strut, chase, communicate, and balance. Nerves extend from a cat's spinal cord into the tail, and are connected to the hind legs, bladder, large intestine, and anus. Yanking on a cat's tail can stretch or even tear the nerves, causing pain and possibly affecting the animal's ability to walk.

A tale of two kitties:

The average length of a male cat's tail is 11 inches (28 cm). A female swishes a tail that averages 9.9 inches (25.1 cm) in length.

The tail acts as a counterweight when the cat walks along narrow surfaces, like an acrobat on a high wire.

Cats communicate with their tails. If a cat's tail is held high, he's a happy boy. A quiver at the tip of the tail means you're the cat's meow. But a feline whipping his tail back and forth may mean he's annoyed and ready to pounce, claws first.
