I would say that I am more of a "dog person" than a "cat person," but my attitude toward dogs is somewhat like my attitude toward children: I like the nice ones and I really hate the nasty ones. On the other hand, I rarely encounter a cat that I positively dislike. The worst of cats, I think, is not as bad an animal as a bad dog.
I am baffled (and sometimes repelled) by people who DOTE on their cats. Okay, the animal may be cute, funny, beautiful, even affectionate in its feline way, but if you went away and were replaced by somebody else, the cat wouldn't miss you, and if you came back again, it might rub against your leg a bit and that would be the end of the matter. A dog would enter into mourning, and would go nuts with joy when its master returned.
