Dogs sit on the car seat next to you. Cats require a private box to go at all. In order to keep a true perspective of one's importance, everyone should have a dog that will worship him and a cat that will ignore him. Dogs greet you and lick your face when you come home from work. Cats are mad that you went.
Dogs sit, lie down, and heel on command.
Cats smirk and walk away. Dogs tilt their heads and listen whenever you talk. Cats yawn and close their eyes. Dogs give you total love forever. Cats make you pay for every mistake you've ever made.
