The average domestic cat has 244 bones in its body, with 30 of these bones being vertebrae. Most of the vertebrae that domestic cats have are located in their spine, which allows them to be extremely flexible animals. Because of the vertebrae that are part of their bone structure, cats are capable of rotating half their spines a full 180 degrees.
Cats have no collarbone, which results in them being able to squeeze through small spaces with little effort. They have retractable claws that are attached to their forelimbs and hind limbs that do not protrude when moving about. Domestic cats have a total of 26 teeth in their mouth, which become fully developed in the first year of their life.
