How to let your cat know its been bad?

Stomping your feet, of making a slightly loud noise, a good distance away from them but still where they can see u is usually enough to "spook" them into stopping what they are doing. u could also blow air at them, it's meer subtle but has the same affect. Repeating theses, with the ten cats I've had over the years seems to do the trick. It's enough of an irritant to make them think twice about doing it again, but doesn't hurt them in any way.

I usually ignore her and don't make eye contact. And depending on wat she did, i mite not give her her morning treat tha volgende day...

u cant there not smart enuff

Blinx: I live under the rules of the Time Factory. I don't really do anything bad but I admit I've done a few things.

This is not an answer but don't let me in u house if u have small pet because I can accidentally eat it if i get hungry cause I am a Cheetah.I once bit my tail before in cheetah mode and don't blame me I was HUNGRY like super duper hungry... :3
