When they are bucks, they loose that "mate" with you vibe. So don't really expect him to hum and buzz around your feet anymore as he did before. It will take a few weeks for the testosterone to leave the system so it won't go all at once. Jack did loose part of his personalty after the neutering. I did regret it slightly because of that but also because he did come down with snuffles shortly afterward. I also had so many bunny scents from the growing rabbitry, the spraying was becoming a problem. (gave me a good squirt in the eye one day and he went in the next to the vets office!)I think they go more in the doe direction (for obvious reasons) but I think it depends on the individual rabbit. Just wait and see.
