Our two bunnies, Smokey and Fred, are male litter mates that we got a couple of months ago. These are the first rabbits we have ever had so we didn't know a lot and have been learning along the way. The first thing we learned is that just because they were litter mates and living together at the pet store, didn't mean they were bonded for life. About a week after we got them, they started to fight and I had to separate them. We took them to the vet to see about neutering to hopefully make them bondable. She wanted to wait a month to do the surgery so we did. I have been reading about bonding in the mean time and have been going with the recommendation to wait a month after neutering to start the bonding process. It has been three weeks now and I am anxious to start. They have been living right next to each other, Fred in an exercise pen and Smokey in an extra large dog crate, with a board in between so they can't see each other. The board got accidentally moved the other day which I didn't notice right away so they have been able to see each other a little, which I decided was okay anyway and deemed it phase I of the bonding process. Phase II was today when I put a "stunt double" in Fred's cage. I had read about it somewhere. It's when you take a stuffed animal with some of the other rabbits fur on it and let the rabbit work out some of the bonding issues on the stuffed animal before being faced with the actual bunny. I am putting a twist on it by giving it to the more submissive rabbit first to get his scent on it (since I can't really get a clump of fur off him) and then I'll give it to the more aggressive rabbit. My hope is that he will take out any aggression he might still have on the "stunt double" and be more settled down when I put the rabbits together. I'll post how things are going and if anyone has any suggestions or comments, please chime in.
