my cat I had in college would do mean things to me too if he didn't get his way.
He would "steal" my jewelry, nice pens and other things he knew I liked or used a lot and would hide them.
at first I didn't know what was going on but then when he thought I was "being good" I would see him go to various hiding spots around the house and out he would come with my trinkets! naughty kitty. he would drop them at my feet and then jump onto my lap for snuggles.
haha, I think he was trying to train me
