Hi, i have 12 rabbits, so am speaking from experince, not as a medical expert. Firstly, bunnies can still make little bunnies up to 4 weeks after neutering, so my vet told me. secondly, my female bunny mounted a neutered male bunny once when first introduced...it is a way that they express their dominance. Bunnies are social animals, and as a rule will settle into a relationship as they love companions. The only combination often DOESNT work is two entire males together,or two entire females together. Hope this helps, It sounds like your too will work out just fine!!
