I checked piggy sites, forums, etc. and could find no real answer. IMHO, most of these pet owners are a tad hysterical.

Anyway, I was given a terrific little piggy this last spring, in return for a favor. I simply put him in the juvie rabbit grow-out pen (7'X16'), and he has run with young rabbits all summer. Now that the weather is getting cold, I am concerned about how much cold he can take. The pen is roofed, it has dry places to burrow and get out of the wind, and he hangs out pretty closely with the bunnies. This is NM, zone 7a, IIRC figs, persimmone, pecans, pomegranites, and rosemary all do fine here. It gets cold, but not Mid-western or New England cold.

I would much rather he stay with the rabbits. If not for the danger, I think he would too. He never was very tame with people.

Anyone else have experience with wintering guinea pigs in a similar climate?
