Why are my female rabbits fighting suddenly, especially at night?

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 Zoomie. Most likely it is because she is an intact female, and is fighting for territory and dominance. She needs to be spayed to prevent uterine neoplasia anyways, so now would be a good time. If she continues to be aggressive to the dog and cat, something bad is bound to happen, so isolate her 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.

The best way to reduce aggression is to have both of them spayed. Spaying females drastically reduces aggressive behavior, as hormonal aggression is most common in female rabbits. Hormones drive them to compete for territory and to protect their home from invaders. I recommend having them spayed before bringing them together.

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.

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.

It doesn't say how old your rabbit is, but if you got her as a baby then she has likely become sexually mature. In female rabbits, this can cause them to become aggressive and not like to be handled. The best and easiest way to solve this problem is to get her spayed. This will remove the hormonal influence on her behavior and help her to settle down. Once she has been spayed you can start working with her and getting her used to being handled and patted again. Keep these sessions short and positive, and use a bit of her favorite food (a little bit of banana is a favorite of my bunnies) to keep it a positive experience.
