Why Should rabbits be spayed or neutered? Neutered rabbits are healthier and live longer than unaltered rabbits. The risk of reproductive cancers (ovarian, uterine, mammary) for an unspayed female rabbit is virtually zero. Neutered males and females are much less likely to fight and suffer injury Neutered rabbits make better companions. They are calmer, more loving, and dependable once the undeniable urge to mate has been removed. In addition, rabbits are less prone to aggressive (biting, lunging, circling, growling) behaviour after surgery. Avoidance of obnoxious behaviour.
