Luckily, Chuck dosen't like people food too much so we never really have any problems. But my sister's cat Trickie stole her husband's baked potato off his plate once when he got up from the table for a second. I guess they were eating at their coffee table. He comes back and it's gone. Trickie is under the sofa growling and hissing at him and wasn't about to give it up. Her husband ended up letting him have it rather than be torn up. Trickie ate the whole thing!
