I’ve had my rabbits Asterlix and Oberlix since very young (going on 4 years together) and they are sisters from the same litter. They are both spayed and have always gotten along and only ever had one or two fights when establishing dominance in a new area as a result of moving and it seemed to resolve without much intervention.
One bun got sick a few days ago (the usual dominant one if that makes a difference) and we took her to the vet. It was determined to be GI Stasis and we were advised to keep them apart for 24 hours to monitor and see if she is pooping normally. To separate them, we had a pen inside their normal roaming area that we put the sick bun in and was still viewable and accessible through the pen but not able to touch.
24 hours passed and she seemed to be getting better so we monitored a get-together time between them before we locked up sick bun in the pen for the night.
This continued until last night. I opened the pen to let the rabbits be together. I wasn’t watching them closely as they had no issues for the past 2 days but as I was in the room I did manage to break up a nasty fight between them. No injuries sustained but lots of chunks of fur were lost. I couldn’t figure out what the cause was but we separated them into their areas again. However, I was woken up during the night to sounds of them trying to fight between the bars of the pen. We put up blankets and towels on the pen until I could attempt to rebond them today.
I thought the attempt was successful. I put them both in the bathroom with my supervision and held one or the other while they got accustomed to each other. I split up a couple tiny nips, but afterwards my usual dominant one was able to mount without an attack from the other and they were grooming and laying next to each other so I thought it went well. This was over a few hours.
I brought them back out to their usual area but switched where they stayed (previous sick bun in the open area with healthy bun in the pen) so they can use their litter box. But they started trying to box each other through the pen again and biting the other when their nose is through the bars.
This is the worst fight I’ve seen between them so far and I’m reading up on every forum and blog post to help, but I’m not sure what rebonded buns look like or what I could be doing wrong or better for them to repair this. My relief from one getting better after GI Stasis has quickly been reversed into anxiety over their fighting.
