Is it necessary to neuter rabbit?

I know the benefits of neutering such as decreasing aggression/mating/territorial marking behavior. However, is it totally necessary if the rabbit doesn’t show any of those negative behaviors?

Not sure how my new 3.5 month old male will change but he seems pretty chill for now.

Also if he does need to be neutered, is it better to do it at 4 months or 6 months? Thanks.

Soon as you see his testicles. In our nearly 17 years of bun experience, the male spraying, stinky urine odor, and all the hormonal reasons you mentioned, were clear reasons to spay and neuter.

I volunteered at a shelter that routiinely euthanized due to over capacity. Oops litters came in routinely. Rabbits were likewise euthanized for aggressive behavior due to surroundings and hormones.

You can also google on cancer risks. Facebook has pics and info from Rabbit Rescues re: abandoned/captured/unsp/eutered rabbits with uterine cancer. It is easier to neuter when buns are younger.
My friend took in a 9 y.o. male, unwanted bun kept in a bad environment. His rabbit-savvy DVM did not recommend neuter/anesthesia/surgery for his elder boy.

Have you been in touch with a rabbit-savvy DVM? Watching our bonded pairs live together for the past 17 years was the best kind of therapy and relaxation. Adorable grooming and bookend R&R.

No, it isn't totally necessary to neuter a male. If it is convinient depends on the individual character. At 3.5 months there's still a lot of growing up ahead.

My free range house bunnys are an intact 10lbs buck and his spayed girl. He has the better litter habits, although at some times there is some spraying to mop up, but normally he tries to discolour his cuddlebun when they are outside.
I have to say that I took him in when he was already 2yo, in his first year he did a lot of spraying, a happy horny juvenile, pee was dripping from the roof of his hutch at times, but well, every rabbit is different.
I know, and like him the way he is. And since I live alone in my own house there's a lot of leeway about what is still acceptable ;)

No aggressions whatsoever. Different to does there is no relevant cancer risk with males (and the numbers for uterine cancer repeated over and over are imho vastly exaggerated as a deadbeat argument, nothing close to them, more like 20%-30% with abnormalties in their lifetime, but, among a lot of others that too is still a valid argument for spaying).

There are those benefits, mostly not getting offspring, and when he gets the spring fever my boy can be a PITA for his cuddlebun, thank god she just shrugs it off. He his much more active than her though (good thing), can't feed them same amounts because her legs wouldn't reach the floor by now.
