The Legs and Feet
A cat's claws are formidable weapons for defense and for hunting. They also are useful tools for climbing and for clinging to precarious perches. Each toe is equipped with a claw, which grows from the last bone of the toe. The claws are hidden most of the time under skin that protects them from injury and keeps them from becoming blunt as the animal walks. A cat sharpens them by clawing rough surfaces or by chewing at the tips. Cats kept indoors will often use furniture if a scratching post is not provided. The retracted claw is held in its "sheath" by an elastic ligament. The moment a cat strikes, a muscle in the leg pulls on a tendon, which in turn pulls on the joint to which the claw is attached, and each claw comes out of its sheath. All claws can be unsheathed in a split second. The cheetah is the only kind of cat that cannot pull its claws completely back. Its claws, like those of the dog, are always exposed.
Male and Female
Cats reproduce so prolifically that there are millions more cats than good homes. Female cats come into heat repeatedly and may become nervous or ill-tempered and lose weight if not permitted to mate. Males wander restlessly, cry loudly to get out, and spray strong-smelling urine about the premises.
To prevent undesired kittens, females may be spayed after 5 or 6 months of age. Males may be neutered after 8 to 10 months to keep them from spraying or wandering. Both operations must be performed by a veterinarian. Neutered cats may need to have their food intake reduced to keep them from gaining weight.
