Wick’s neuter was delayed until his testes descended, which ended up being very late (8 months), and he didn’t get neutered until a month later. Up until the snip, he was a general nonhormonal rabbit in terms of behavior. So it’s not unheard of, but definitely uncommon.

Hmm I’m starting to wonder if it could be a small breed thing because Kurotta is also still unaltered (8+ months old Nethie), and he doesn’t display any bad/hormonal behaviours. He doesn’t really pee or poop outside his litter box/cage (apart from the occasional 1 or 2 accidental poops), doesn’t spray or hump, is not destructive and only circles when he is very excited during treats time. He enjoys pats and isn’t aggressive unless we try to pick him up. He will only nip if he wants you to move, but that’s more like a communication method rather than hormonal behaviour.

I have the exact same concerns as you, which is why I am delaying my bunny’s neuter for now until I think it through properly. So yes I guess our boy buns could all be outliers here.

When I first got Bam he wasn’t neutered, but he was fully grown (2 kg = 4,4 lb) and not neutered. He didn’t show any hormonal behavior until after a year, almost exactly. Then he very suddenly and surprisingly fell in love with my dog and started courting her. It went on for a couple of month but didn’t subside (it actually got worse), so I had him neutered. After two weeks the infatuation was gone (much to my dog’s relief) and Bam returned to his “old” self.

Single male rabbits, especially if they’re an only pet in a household, don’t necessarily get very hormonal. We have had a few examples of intact males living to a ripe old age and never displaying any territorial peeing, circling, grunting, pursuing, humping etc.

The main health risk with a single intact male is testicular cancer. Testicular cancer used to be rare in rabbits, but in later years, it has started to become less rare (although it’s still not common). That’s because it’s a disease of the elderly in rabbits, and rabbits nowadays live longer lives due to better care and health care.

Bombur was displaying hormonal behaviors at 7 weeks (and he’s a Holland Lop, so another dwarf breed). Asriel, on the other hand, never showed any hormonal behavior. We knew his hormones had kicked in though when Bombur didn’t want to let up on mounting him and they got into a squabble. We got them fixed the same day. I think Asriel is acts more hormonal now that he’s fixed though.

It really depends on the bun, some are much less hormonal. It could be because he hasn’t been around other buns since he was young so he doesn’t feel the need to mark etc.

Very interesting to read all these replies! Adding my two cents, Sam is a lionlop (but I suspect a lion-mini-lop, if those exist? since everyone tells me he is pretty tiny!) so maybe the small breed theory holds true – he’s not neutered and barely shows any hormonal behaviour either. Great litter habits, no spraying. The only thing he does is occasional circling & honking around my legs haha, but if I get down and cuddle him he always settles down immediately. So yes, to answer your question I’d say he fits the profile of an intact male, laid back & no real behavioural issues
