One of my wife's teaching colleagues has a dog and a ferret at home. The dog and ferret love to play. The teacher has been keeping the ferret in the cage as she has some kind of pipe drain in the bathroom she is afraid the ferret my get trapped in. She just move recently. Turns out the dog has figured out how to open the cage latch so they can play.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
