A female rabbit. All domesticated rabbits have evolved from the European Wild Rabbit (a different species than our North American cotton tails). The rabbits that were turned loose and overran Australia were European Wild Rabbits. They are basically bigger and actually build their own warrens, whereas our cotton tails live solitary lives above ground. The San Juan is a variety of domestic rabbit that has been bred back to look and run a lot like the wild variety. A lot of beaglers use them because they are the closest thing to having a real cotton tail. They got their name from the San Juan island (somewhere off the NW U.S. coast) where they have gone wild (feral).
The reason I shied away from them as they are not bred or originally made for heat. At about 70 F they need fans and sprinklers which is too much investment for a backyard project for me. My cals bounce around like nuts and dive though when let out to "play" (cleaning cages). If you get them please update I'll like to hear how it goes.
Never settle.

The guy I get them from doesn't have any problem with them during the summers here (and it can get up to the high 80s and low 90s). I think he keeps their hutches in the shade. They are a little jumpier, but they seem to act like normal domestics otherwise, just a lot faster. I think they can get up to around 4-5 lbs. -Joe
