I don’t see in your explanation which rabbit is disabled and what the disability is. Could you please explain?
The mounting definitely could be hormonal but after the hormones subside you should expect the possibility of continued mounting until they work out dominance. They use that as a move to establish dominance and females will actually do it too sometimes.

Oh also you might consider putting a second barrier between them so they can’t directly harm each other through the bars, like a second pen or something so they have a few inches.

I second pinkiemarie.

Also want to mention you shouldn’t let them interact directly unless it’s in neutral territory during a bonding session. Sorry I wasn’t clear on that from your description, but thank you for filling out the template!

In any case, it sounds like they are getting a long relatively well. Are you hoping for advice on the next steps to take?

Was this mounting that was *eh-hem* “productive”, right after his neuter?

I would still do neutral space because the dynamic between them might be different in a neutral area. You might find the mounting actually subsides if they are in a completely neutral space. Mounting also might be a necessary part of them sorting out their  dominance, in which case you need to allow it to happen, as long as it isn’t overly stressing or hurting either bunny. Also stop face mounting to prevent any bites to delicate areas.

So I think what I would try, is put them in a neutral space together and see how that goes. If the mounting gets to be too much, try gently moving the mounting bunny off and positioning them side-by-side with the other bunny, and pet them to calm them. Then pause for a few seconds and see what happens. Don’t allow them to circle or chase (I usually stop chasing after a couple seconds), and make sure to prevent fighting. I think in your case especially, do lots of petting to keep the bunnies calm.

For first sessions I like to set some short time goals (5 or 10 min tops) for a few sessions and then go from there. Always try to end on a positive note (such as both buns relaxing or mutual petting). If those sessions go well you can start increasing the length of the sessions.

If his mounting never slows down and seems to be stressing her out, he might not be a good candidate to bond with your disabled girl. But hopefully it was just hormonal and/or a phase they need to get through with bonding.

Are you sure he’s neutered? There really shouldn’t be anything produced if he’s neutered… so I’m a bit confused by that.

The petting during bonding sessions seems (in my experience) to be a bit different than regular petting because the bun usually interprets it as they are being groomed by the other rabbit. I’ve had shy buns that don’t normally want pets accept them if it’s during bonding and they are next to the other bun. If he moves away that’s OK too.

Sometimes neuters and spays can be incomplete. A certificate doesn’t really prove anything except they did an operation they think was successful. I’d go to your own vet and get it confirmed because he shouldn’t be anything coming out of him.

also, how long do you let him mount for? If he’s able to finish, it seems like he’s mounting for too long. This could end up distressing her and leading to a fight eventually. I would stop him after a count of 5. Especially if she has weak hind legs, I just wouldn’t want that kind of pressure back there for so long on her.

Yes, it’s just that he’s finishing his business is what’s just confusing and weird. Mounting is totally fine. If he was properly neutered and it was only that short time ago, he’ll be a bit more humpy anyways just because the hormones are balancing themselves out.

Unfortunately bonding can be a slow and agonizing process. It all depends on the buns 😂

Yeah rabbits don’t take very long… From what I heard from someone I know, a boy rabbit totally could be done in like 10 seconds! My buns are both fixed so if they mount it’s totally a social behavior and can go on much longer than that if I don’t stop them.

Sometimes boys will groom in preparation to mount. Typically the one mounting is the dominant one… but it does sound like it’s still hormonal (or maybe even an incomplete neuter?) which would make it less clear. A request for grooming is a dominant move, usually the submissive rabbit will groom first. That said, in many pairs it’s hard to tell which rabbit is dominant because they both show a combo of submissive and dominant behaviors. I’m convinced sometimes they both think they are top bun. 🙂

For long sessions I usually stick to one area (sometimes new areas mean they have to sort things out all over again). Part of them working out their relationship means being bored together. But you can provide lots of toys (new neutral ones) and other things to chew on to prevent them from getting too bored.

Regarding the potential semen production, males can store sperm for up to 6 weeks after neuter, so I would give it some more time before doing more sessions. That will make sure his hormones have really settled and he doesn’t have any more saved up.

I second what Dana said, and during that time you could try some pre-bonding as well.

Hahah that’s good!

I thought you weren’t going to do any more sessions until his hormones have settled for 2 weeks more?

You’re boy is too hormonal for bonding to be productive at the moment.
He isn’t bonding , he’s trying to breed with her.  Some boys take a longer time for hormones to drain but it is usually 6 to 8 weeks before they should be bonding after their neuter.

While he is like this bonding is almost a complete waste of your time, and unnecessary stress for the buns. Stop bonding for another few weeks, and let his hormones settle. During this time you can cage swap them and let them settle and get used to both the house and each others company.

Cage swapping, scent swapping and letting him settle into himself is the best way forward for now. He might try and mount in future, but you can and should discourage him from this considering her weakened back legs, ie when he starts acting like he is going to mount either distract him , or place your hand over her back so you are carrying his weight not her. She is obviously being compliant and letting him, but like A&B said, too much of this is likely to start a fight (or cause your poor girl pain or stress or both). Mounting is part of bonding but if it is stressing the other bunny, most bonders will say dont let it happen, in your situation your bun has a disability so even if she is not showing obvious distress  you should still stop it, as she is not able to do move away or react herself

Oh I’m so glad things are going well! Sounds like you got an easy bond which is so nice. With the continued chasing just keep a very close eye on them because it could turn into something where one of them gets hurt in the blink of an eye, and don’t be afraid to separate them for a couple of hours if they need it!

It’s entirely possible that they’re just playing! I’m just warning caution and to keep an eye and ear out because aggression can happen for a while after bonding while they’re still finalizing their dominance hierarchy.

FYI I just edited to remove the swear word.

Most important is to trust your gut. Other signs they are bonded are: sharing food (like, they can yank it out of each other’s mouths), sharing litter box, snuggling, grooming each other, and generally being in each other’s personal space without incident.

Signs they need more work: fast chasing, fur pulling, nipping, or general “tenseness”. You want to see lots of positive behaviors and no negatives.
