Cats vs Dogs A cat is a small round, fuzzy creature which we call selfish. An animal can not be selfish. Only humans can be selfish. A dog is an animal that most show preference to. Sure, a dog will keep you company when you are upset. And when you aren't. We call dogs giving. An animal cannot be selfish, nor can it be giving. But when you think about it, which creature would hurt you the most? When a dog's teeth sink into your flesh. When a cat scratches lines down your arm. People scratch themselves all the time. We scratch when our arms itch. But we don't bite. That's why I find it repulsive when people say dogs are so much like us. Dogs act like servants to humans. Cats are a wide range of personalities. And like most of us, cats are not pushovers.
