My rabbit is mounting and harming my other bunny. What to do?

This unfortunately happens sometimes where their bond is broken around the time they reach sexual maturity. It is wise to keep them seperated, because the mounting seems like aggressive behavior. However, I would have a vet double-check the sex of these two. I have seen many rabbits that were mistakenly identified as females, when they were actually males. This would also explain the mating behavior. You should also consider having them spayed/neutered at this age. I prefer to do this surgery around this age and it's quite safe when in an experienced surgeons hands. They will often cease the aggressive/mounting behavior after this procedure is done; and it saves from having a litter of unwanted bunnies...which is a big problem. I hope that helps and you can get this problem sorted soon.

Thanks for reaching out. Not all individuals get along, especially in confined areas. As young rabbits mature and hormone levels rise, territoriality and dominance are fought over to establish. Spaying the rabbits is necessary anyways, so now might be a good time. Keep separated for now. Good luck.

Thanks for reaching out about Bun Bun. This question has been addressed once before but there recommendation is to have Bun Bun spayed, and Fluffy neutered also (if not). Intact female spays have an increased incidence of uterine cancer but also tend to fight more. Talk to a veterinarian in your locale. Good luck.

Thanks for reaching out about Bun Bun. A wound needs to be kept clean. Gently clipping hair around the wound to prevent hair contamination. Gently clean with mild soap and warm water. Do not apply any topical antibiotics as many can infect the rabbit's gastrointestinal tract if ingested. The rabbits might need to be separated. Altering both rabbits might decrease aggression. If the wound worsens or Bun Bun becomes ill, a veterinary visit is mandatory. Good luck.

Thanks for reaching out about Mr. Magoo. It is unusual for rabbits who are castrated to become aggressive after living together for some time. Environmental stresses can shift hierarchies and start aggressions. Adrenal tumors can produce testosterone and lead to aggression. Not all rabbits get along, forever and they might have to be separated. An examination with a veterinarian with experience in rabbit could probably help you. Good luck.

Mounting behavior is not unusual but I would recommend to have both rabbits checked out to be sure they are both males! You definitely don't want a bunch of baby rabbits! Male rabbits can sometimes become aggressive so neutering them is a good option to decrease aggression. You can discuss the surgery with the doctor during the visit to see if this is a good option for you.

You need to separate the bucks (males). The adult sees the younger buck as a rival, especially in the presence of the does (females). It would be recommended to separate the bucks from each other and from the does. A doe can begin to breed as early as 6 months of age. Leave them together and you may find yourself overwhelmed with rabbits very quickly.
