It is too bad about the guinea pigs. They are delightful critters to keep.

They don't climb much, and I've never had one dig. With those qualities, I'd keep a colony in the greenhouse if it was worthwhile. The Peruvians eat them, but the strain they raise is larger. The little piggies avail in the American pet trade really aren't worth the trouble to butcher. My understanding is that the hide is SO though, the skin has to be singed off.

Maybe for feeding a komodo dragon or something? (just kidding).
Would love an excuse to keep more piggies.
