Altered rabbits tend to be healthier and live longer than unaltered rabbits. Altered rabbits also make better companions. They are calmer, more affectionate, and steady once the undeniable urge to mate has been removed. Neutered rabbits are less prone to destructive and aggressive behavior after surgery. Unneutered male rabbits spray, and both males and females are much easier to litter train after they have been altered.
Rabbits are social animals and enjoy the company of other rabbits.
But unless your rabbit is altered, he cannot have a friend, either of the opposite sex or the same sex, due to sexual and aggressive behaviors triggered by hormones. Altering expands the rabbit s social circle. Females can be spayed as soon as they sexually mature, usually around 4 months of age, but many veterinarians prefer to wait until they are 6 months old, as surgery is riskier on a younger rabbit. If a rabbit is 6 years old, anesthetics and surgery become more risky. Unfortunately, the vast majority of veterinarians aren't experienced with safe rabbit surgery techniques.
