Of Cats and Dogs.

The primary psychological difference between any given cat and any random dog is that dogs can't hide their emotions. If a dog is angry, it's obvious. Cats can hide their anger and take revenge later. I shaved a portion of the family cat's tail once, and he acted normal towards me for two days while he plotted revenge. His revenge was perfect, he sprayed my pillow.

Dogs also have a sense of remorse. We can look at our dog and see right away if he got into something in the kitchen when we were gone. He hangs his head low, and you can see in his eyes that he feels like dirt.

A cat has no sense of remorse, no guilt whatsoever actually. If you come home to a cat ravaged kitchen, blinds torn to shreds, food eaten and look angrily at the cat, the cat just looks at you with an expression that says:

"What are you lookin' at? Get me some dinner, I will be in the front window plotting my escape.....You filthy PIMP! "
