Someone has said that the domestic cat gives us an opportunity to safely caress the tiger. How true!
Except for size, cats are all built pretty much alike. They act alike, too. (Turner and Antón)
Paleontologists are still working out exactly how that beautiful shape evolved (Werdelin and others), but it’s ideal for stalking and ambushing prey.
The cheetah is the only specialized pursuit predator in this family (Andersson and Werdelin), but all cats are good at short sprints. In general, feline leg length is a compromise between short legs for power and long legs for speed. (Kitchener and others)
The fact that cats are meat specialists has shaped their mouth and skull. (Holliday and Steppan)
They have lost most teeth that aren’t used for processing flesh. Adult house cats only have 30 teeth, while dogs, who can grind food as well as slice it, have 42.
Cats have shorter faces than other carnivores because meat is 70% or more of their diet. (Holliday and Steppan) Since they use their fangs to kill prey, this shortened distance to the jaw joint protects the teeth and increases the overall bite force. (Kitchener and others)
Unlike other domestic animals, house cats haven’t changed much. (Hart and others; Van Neer and others)
They are more colorful and a little more nimble than their closest wild relative, the wildcat (Montague and others), but the biggest difference is that a house cat raises its tail in a friendly greeting, something no wild cat has ever been seen doing. (Bateson and Turner)
