Neutering in males is mostly for behavioral reasons, and is much less invasive than spaying. So as long as your bun isn’t ever interacting with any other bunnies, and you are happy with his behavior, I don’t personally see a need to rush to do it. But if you start seeing an uptick in hormonal behaviors you will know why. Sadly a lot of male bunnies get surrendered to shelters because they start showing marking, spraying etc. and the owners don’t realize these problems are typically fixable (no pun intended lol). Sometimes those behaviors get ingrained and stick around after neutering, but if you neuter soon after you notice them they should subside.
Are you 100% sure “he” is a “he”? It’s worth double checking!
