I had an experience with a broken bond (after 5 months of peace, no obvious trigger), and I opted not to try to rebond them, because I felt that the bond wasn’t particularly strong to begin with (I had also used a marathon technique) and I felt that even if rebonded I would never be able to trust them.

My understanding is that to rebond after a serious fight, you must separate them out of sight and smell for 3 months, to allow them to forget each other, and then start over at square one (short dates in neutral territory). There is no guarantee that you will be able to bond them…. Were they very closely bonded before the fight? Do you know what might have triggered the fight? Any changes to your household?

Personally, given that the bond was very difficult to begin with, and the seriousness of the fight, I wouldn’t try this pairing again. But that’s just me, and I don’t know your buns. There are many that believe all bonds are possible, but it probably isn’t worth the stress and risk to you and your fur babies. Are you able to have them live side by side, but separate, permanently?

I don’t have any experience with trio’s, so someone else will have to chime in on that one.

The adoption counselor I talked to the other day about finding a new mate for my rabbit said that usually for trios two girls and a boy works best because two boys will have a difficult time sharing one girl. I’m sure there are exceptions to this though! My suggestion would be to consult your local House Rabbit Society or Humane Society if you plan on trying to add another rabbit or even just reach out to them for advice on bonding males together. Typically they’ll have the rabbits go on “bunny dates” to see which rabbits are a good fit in hopes that bonding will be more successful. I hope something can be figured out soon and relieve some of your stress! 

Just as a note about red urine, it’s not necessarily blood:

Thanks for the update, glad to hear your boys are doing well.

Again, I don’t have any experience with trios, but I’ve heard they can work, they can also be a challenge. It may be easier to have two pairs, which many people have. It’s really up to what you are up for, and what your household can handle!

Many people report having two solo buns living side by side very happily, so if your guys seem happy, then don’t feel bad. You can also try giving them a stuffy, which some folks say their solo buns love to snuggle with.

Are there any tricks with stuffies and single buns? I got mine a sheep stuffed animal at the same time as we adopted him. It’s been a year, and he still happily ignores said sheep. Never even as much as leaned on it.
