Kitten, get off of my computer. You don’t know how to use it, you aren’t even looking at the screen.
Cat, get off of my cookbook. I don’t think you can read, but even if you can, I know for a fact you’re a lousy cook, that tuna you made the other day tasted a lot like rat.
Cat, get off my toilet. You’re obviously using it as a seat. You don’t even like toilet paper, you just spend all day attacking it!
Kitty, get off my synthesizer! You don’t even know how to play it. You haven’t taken any lessons!
Cat, get off my Tupperware. I need it for the casserole.
