Unlike a man, a cat can fend for itself. If a cat gets lost, at least it has a tag on it to tell whoever finds it where it lives. A cat is loyal. There's a better chance of finding a cat that is willing to read a book that doesn't have any pictures. Cats always greet you when you get home.
Cats are more intelligible in the morning.
A cat's idea of a good time is a game of string and a good belly rub. Cats don't come with in-laws. A cat won't steal anything but your glasses, your golf balls, and your heart. Cats drink less and snuggle more. Each of a cat's nine lives is worthwhile.
