Cats can be cooperative when something feels good, which, to a cat, is the way everything is supposed to feel as much of the time as possible.

Cats make one of the most satisfying sounds in the world: they purr. [...] Almost all cats make us feel good about ourselves because they let us know they feel good about us, about themselves, and about our relationship with them. A purring cat is a form of high praise, like a gold star on a test paper. It is a reinforcement of soemthing we would all like to believe about ourselves -- that we are nice.

Try throwing a ball just once for a dog. It would be like eating only one peanut or potato chip. Try to ignore the importuning of a Golden Retriever who has brought you his tennis ball, the greatest treasure he possesses!

Two would actually do it- two magic words that could replace all the religions in the world- two wonderful words that embrace all the powers and all of the energy we need to survive with each other and with our planet and with all the world's living creatures- don't hurt.

Dogs are not our whole life, but they make our lives whole.

Cats are a tonic, they are a laugh, they are a cuddle, they are at least pretty just about all of the time and beautiful some of the time.

Dogs have given us their absolute all. We are the center of their universe. We are the focus of their love and faith and trust. They serve us in return for scraps. It is without a doubt the best deal man has ever made.
