Why is my spayed female rabbit humping her companion? Is it normal?

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. They are probably vying for dominance and might have had a fight, where the vulva could have been bitten. Rabbits are induced ovulators, and need to be spayed to prevent uterine cancer, which is very common. They need to be kept separate, and spayed. Good luck.

Humping, especially in fixed females is just a show of dominance. They are trying to figure out who is boss. As they get older this may decrease but in some siblings may occasionally happen for years. Thanks for using Petco Pet Education Center, formerly Petcoach.

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.

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 using Petco Pet Education Center, formerly Petcoach! It is a display of dominant behavior. This is generally not a big concern but I would try to avoid as much as possible as she could hurt the kitty by mistake. Have a great day!

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.
