Since you were gone for a few days, im assuming you had someone watching them for you. Do you know how the person watching them took care of them? Its likely that person didnt fallow directions carefully enough and caused your two boys to break their bond. Youll want to find out what in order to combat this in the most successful manner. Until then, keep them completely separate. The more they fight, the less likely it will be that youll be able to bond them again. Stop letting them out together, no excuses. Youll have to alternate their free roam time. They will need to be separate for atleast two months. After those two months, and after you learn what happened while you were away, you can try to rebond them in a small neutral territory, such as the bathroom. Read up on how to bond (its very simple, but may take a few weeks, to a few months, and for some: a few years) and start the process with them. If after the separation nothing gets better, then whatever happened while you were away and all of the fights you allowed them to have for the last three weeks caused them to completely break any bond they can have together. Good luck!

Hi,I have 2 male bunnies(Scout&boo),4 months old.They’re brothers and we haven’t got them neutered yet because the vet says they wouldn’t be able to handle the trauma(caused by neutering).From the first day,they have been inseparable,they used to eat together,sleep together,groom each other and follow one another.Last night they were chasing each other,which seemed normal as we were used to them running all around the house but they got into a vicious fight and one of them seriously damaged both of the eyes of the other and there was furr everywhere.I took boo to the vet today and thankfully he’ll recover soon.But now whenever they see each other,all they do is fight.I tried stopping them and ended up having cuts on my hands.What do I do?Is there any chance that after neutering they’ll be able to live together like before?

Hi Tasneem. I don think piggybacking on threads is allowed on this website, so youll want to make your own thread in the behaviors forum https://binkybunny.com/FORUM/tabid/54/aff/3/Default.aspx

I will try to help though, since it sounds like your little boys need it. Is your vet certified to work with rabbits? Have they gone to school to work with rabbits, not just cats and dogs? It takes extra training. If not, youll have to find a vet that is certified to work on rabbits
There are many benefits to neutering male rabbits. One big example is their hormonal will to fight drops to a mostly complete stop. It can take up to a few months for the hormones to fizzle out after a neuter, so they will have to be completely separate until then, but it really helps with bonding
Youll have to keep them completely separate for a few months (two to six months, dont let them near one another) anyway to help them drop their grudges before you start trying to bond them again. Right now they are likely fighting over territory due to not being neutered and letting their hormones drive them. Its very common in bunnies who are not spayed or neutered
After they are neutered, healed, and have had 2+ months completely away from the other, you will want to bond them in a room in your living space where they have never been before. Start in small areas (example: bath tub+no water), then move to bigger areas (a room), then to their final living space together (their cage/free roam room). Start with small sessions often (2 minutes, multiple times a day), and increase over the course of a few weeks and months to longer sessions less often (4+ hours, a few times a day). A good idea would be to read the “bonding” forum here while they are separated so you can get some good ideas on how bonding works Good luck!
