Klepto-cat

My sister adopted a stray kitten a while back. We've come to discover he has a strange habit...he steals things and hides them in a corner he has set aside for himself. These things range from cloth pieces, little ornaments lying around the house and even other cats' toys. The most alarming thing we saw is that he tries to sneak into people's bags also to pick out his loot. Imagine the horror if guests see him do that and think we've trained him to steal :p
