Cats are to dogs what modern people are to the people we used to have. Cats are slimmer, cleaner, more attractive, disloyal, and lazy. It's easy to understand why the cat has eclipsed the dog as modern America's favorite pet. People like pets to possess the same qualities they do. Cats are irresponsible and recognize no authority, yet are completely dependent on others for their material needs. Cats cannot be made to do anything useful. Cats are mean for the fun of it. In fact, cats possess so many of the same qualities as some people (expensive girlfriends, for instance) that it's often hard to tell the people and the cats apart.
Getting down on all fours and imitating a rhinoceros stops babies from crying. (Put an empty cigarette pack on your nose for a horn and make loud "snort" noises.) I don't know why parents don't do this more often. Usually it makes the kid laugh. Sometimes it sends him into shock. Either way it quiets him down. If you're a parent, acting like a rhino has another advantage. Keep it up until the kid is a teenager and he definitely won't have his friends hanging around your house all the time.
