Bee...I once had a cat (Mara Jade) who wouldn't touch people food unless it was chocolate donuts. She was nuts over them. And lord forbid a coin hit the floor. She would come running from anywhere in the apartment and snap it up. I would later find it in the water dish. Go figgah.
Madmardigan LOVES tortilla chips. He will actually steal them out of the bag if you don't watch closely. And Sheldon will put ANYTHING in the water dish (bracelets, coins, candles, frig magnets, cat toys). Maddy is Mara's biological son but Sheldon is no relation. I think she was reincarnated!
