I was watching funniest videos on t.v. yesterday and they showed one cat waiting at the slot in the door for the mailman to push mail through. the cat would grab a piece and go off with it. I don't know what happened to the mail after that, they didn't show it. I thought only dogs did that!! Oh my!! And they also showed a cat stealing a whole loaf of bread and attacking it on the floor. I think the bag was what the cat wanted, not the bread.
