You’ll want to have him in a limited area, with nothing to jump or climb onto for the first bit. You’ll be wanting him to let his bits heal. Boys heal faster than girls do, so it won’t be long before he’s wanting to be let out to play and such It takes about 4 weeks for the hormones to die down, so don’t expect over night changes with anything. If he is already bonded, you’ll probably want to keep them together, if she won’t bother him or try to clean his surgery area. Otherwise the change in scent will likely cause you to need to rebond.

He will be back on his feet just a few hours after the surgery.

One thing you should be aware about is that males do have a tendency to go completely hormonally crazy about 3-4 weeks after the neuter. So don’t feel discouraged if he suddenly starts peeing everywhere or be a real pain in the #&%& It will pass.

I haven’t seen any change in behaviour in my males, besides the fact that humping is no longer their favourite pasttime.

It depends on the relationship between the male and female. Most couples do not need a break from each other. Just keep an eye on him and make sure he doesn’t try to hump her the first week or so. But ask your vet when you can expect the wound to be completed healed. I really don’t think it takes a long time. It would be a shame to separate them if they are used to being together and she doesn’t let him hump her anyway.

If Othellos testicles have descended, he can actually be done now, though it does depend on what age your vet feels comfortable doing them of course.
Have you a rabbit experienced vet? One way we can tell is if they advise you to fast the rabbit before surgery. If they do, then this is NOT a rabbit savvy vet as rabbits should never be fasted. Sometimes an uninformed staff member may give the wrong advice based on cat/dog protocols so if you get given the wrong info, check that the vet themselves are in the know.

I just read in your bonding thread that your 2 were recently put together. You’ll just have to keep a close eye on them after his surgery. As karla said, sometimes post-neuter they can actually act more hormonally driven for a short time. This could cause Othello to chase and want to mount. So the risk is he could open his surgery site, or Calypso could fight him. So I think the best way forward is to keep a close eye on them. Since their bond is so new, if you do have to separate them all is not lost. You’ll be able to patch it up within a week or two.

As far as healing time goes – Males are SO much easier than females. Jackson looked remarkably good after his neuter, whereas Coco looked like death warmed over for at least 3 days post her spay.

Mine were not bonded – and it definitely took 4 weeks for Jackson for his hormones to calm down. I saw a great deal of hopeful attempts to mount and the crazed frantic looking for Coco ( I was having them visit between gates so they could sniff but not fight) It wasn’t until he calmed down that she was wiling to tolerate his behavior.

Coco never tolerated being mounted. Never. I have seen her mount him once or twice, but she has never stayed still long enough for him to complete an attempt.

I hate to say it but I have noticed almost no differences since I got my boy bunny (also a mini rex) fixed! He had issues with peeing on stuff before, and still does so (and it’s been almost 2 months). He has become calmer and cuddlier, I guess. He was also over 1 year old when I got it done since he was a rescue and previously unfixed. He seemed unusual because I never saw him try to mount anything, and he didn’t growl or lunge or show any territorial behavior either. It’s a mystery I guess, every bunny is different. They definitely need to be fixed though. And what the others said above is true, when I picked him up from the vet you couldn’t even tell he had an operation, he was jumping and eating right away. The operation for male bunnies is not very invasive compared to the female operation.

My boys got into better litter habits after their neuter. I also found my Mini-Rex became less aggressive and territorial but this happened very gradually.

My advice is to make sure to check the wound 2x day and keep his housing area very clean and dry.
