yes...must have at least a pair; they will literally die from loneliness, even amongst other animals. They can be left to their own devices, with automatic waterers and enough hay, although we always have a hand with things here if we are going to be away more than 24 hours.
The mating ritual, as i think I mentioned, can be somewhat disturbing...it involves the male humming, loudly, until the female decides to be willing and...er, assume the position. And then the male...continues to hum. For like 20 minutes. Or more...until the Deed is done and dismount occurs.
Once pregnant, or pushed far enough, the girls will not respond to the humming very favorably...spitting generally ensues, although I've witnessed some rather sharp kicks as well...
