CAT

Cats are similar in anatomy to the other felids, with strong, flexible bodies, quick reflexes, sharp retractable claws, and teeth adapted to killing small prey. As crepuscular predators, cats use their acute hearing and ability to see in near darkness to locate prey. Not only can cats hear sounds too faint for human ears, they can also hear sounds higher in frequency than humans can perceive. The usual prey of cats (particularly rodents such as mice) make high frequency noises, so being able to pinpoint these faint high-pitched sounds gave cats' ancestors an evolutionary advantage. Cats also have a much better sense of smell than humans.
