Sterilization

                         -------------



Pet rabbits not intended for breeding should be sterilized at any

time after 4 1/2 months of age.  Male rabbits (especially of the

dwarf varieties) have a tendency to become aggressive upon

reaching sexual maturity.  Neutering (castration) is the best way

to reduce the severity of the problems (biting, urine-spraying)

seen in sexually mature male rabbits.



Female rabbits should be spayed (ovariohysterectomized) to

prevent unwanted pregnancy and uterine cancer.  Uterine tumors

are the most common type in female rabbits and often are

associated with serious blood loss.  Spaying female rabbits may

also help to prevent or reduce territorial aggression among

females.
