He was a teacher on Cos, an itinerant practitioner of medicine, and the presumed author of a number of treatises.
Males: Castration is a relatively minor operation, which can be performed as soon as the testicles descend (10-12 weeks) although most vets wait until the rabbit is 4-5 months old. The testicles are removed via the scrotum or the lower abdomen.p to 80% of unsprayed female rabbits develop uterine cancer by the age of 5. Females who are not spayed when young and in good health may have to undergo the operation as an emergency in later life (e.g. cancer or pyometra) develops.
