We once had a pair of very inbred Siamese cats who managed to snag a frozen chicken from someone's kitchen and drag it back to the house we were living in at the time. It was a hot night and I assume that some poor soul was defrosting the chicken near an open window. It arrived much worse for wear and still too frozen for the cats to eat. They were furious when I took it away and threw it in the garbage, then put a large rock on top of the lid of the garbage can.

Amazing what one can do when determined.
