Cute aren't they ... Rabitts, especially females are terratorial. Keeping mature females in a cage that size , I would expect WW3, and one may not be alive for long after the tiff. I wouldn't recommend keeping mature males together to maturity , or male + female together in a single cage as fur will soon fly. Also, take the female to the male's cage for breeding , not male to female's cage, or she will attack the male and injuries are sure to follow.
