I apologize for this being so long.
I have a male neutered rabbit named Buster, and I recently adopted Lola a female spayed rabbit from the shelter in early October.
Buster and Lola sort of chose each other during their rabbit speed date, and the volunteer advised that Lola would probably be the easiest rabbit for him to bond with. She did warn me that Lola is a bit cage protective but that behavior would go away very quickly, but unfortunately she still is till this day. Lola is very cage and food aggressive, (she boxes, bites, growls when I feed her). I’ve tried scatter feeding her, showing my dominance, but nothing works sadly. She has gotten a bit better, but it’s a very up and down process.
So I started with the bonding sessions and was advised to start out very very slowly: 2 minutes a session for a week, then increase to 5, 10, 15 minutes. By the end of two weeks I increased the sessions to an hour. The first hour session went pretty well, Lola started grooming Buster (but would then lunge and nip at him). However the next hour session, I moved them to another location because the volunteer at the shelter told me that the tub is not the best place for their feet. I moved them to another location, and that was when they had their first major fight (no blood, but lots of fur pulling). I separated them for a week and started again in the tub, very slowly. I did 5 minute sessions for a week, then 10 minutes, and increased very slowly to 30 minutes after two weeks. They were doing well mostly sleeping in front of one another, however I noticed that Buster’s bumped his nail and started bleeding during a session in the tub so I decided to find another location in my house.
I moved them to another neutral location in the house that is slightly smaller than the tub, but that’s when they recently had their 2nd major fight (it was so bad that Lola started screaming). It was terrifying and at this point I don’t think it would make sense to try again. I checked each for bites and bleeding, both of them are ok, except Lola has a small patch of hair missing. on her head.
The most frustrating part of all this is,is that even with the major fights, Lola seems to be the aggressor in every scuffle. Buster would attempt to get close to her, and she would lunge at him, sometimes nip him. Every session would start out with Lola lunging at Buster, never vice versa, and during every session whether they were 2 minutes or 20 minutes, Buster would be get kind of annoyed at her lunging and attack her back. When she started grooming him, she would then lunge at him, and they would start scuffling and grunting at each other. I’ve tried pre-bonding by switching their living quarters, rubbing a shirt on Buster and giving it to Lola, feeding them together as they face each other through the barrier. Everything.
TLDR: Aggressive female rabbit, trying to bond with more docile male rabbit. Took bonding very slowly but they had two major fights. Feel like giving up, any advice would be helpful. Again, sorry for the length.
