My boyfriend's cat, Buddy, loves the milk container caps and, yes, we find them under the fridge all the time! He will also take old shoelaces and sashes off of any of my clothes (I choose to think that I donated them to him, not that he stole them) and do the thing where he holds them down and pulls on them, carries them through the house like prey, and throws them and jumps. Of course, when we catch him doing this, he immediately stops and looks at us as if to say, "You did not see me acting silly. I am FAR to dignified for that!" It's hilarious!
