Interestingly enough, the cat family split from the other mammals at least 40,000,000 years ago, making them one of the oldest mammalian families. All cats share certain characteristics that are unique to the cat family. Cats are pure carnivores. In fact, if you were to design a creature to live from hunting mammals you would have trouble doing better than the design of the cat. If you know cats at all, you know that they have powerful jaws, long, sharp teeth, and claws that draw back into their paws when not in use.
Cats hear extremely well.
Their eyes are adapted for vision in dim light for hunting just before dawn and just after dusk, the prime hunting periods. Cats have five toes on each front paw, but only four toes on each back paw. Cats have true fur, in that they have both an undercoat and an outer coat. Contrary to popular belief, the cat is a social animal. A pet cat will respond and answer to speech , and seems to enjoy human companionship.
