When you sternly rebuke your dog, he hangs his head, cringes, and does that weird little frantic tail-wagging.
When you sternly rebuke your cat, he looks at you like you don’t have the foggiest idea what you’re talking about. Of course he shredded the paper towels! You got a problem with that?
Disclaimer: My cats simply don’t do things like that. They just get yelled at for fighting.
