Dogs just won't let you throw them. Cats let you kick them when you're stressed out. Cats will wait until you've read your morning paper before tearing it to shreds. Dogs just crash right in front of the screen. Fewer cat owners suffer from 'Flappy Tail' lacerations than dog owners.
Cats bury their crap.
Dogs dig up others'. Cats have better things to do than stick their nose in your crotch. Cats lay on the car in the heat. Dogs in heat lay the car.
