How to castrate a cat
Make an appointment with your local veterinary clinic.
Castration is a surgical procedure that must be performed by a veterinarian. It is illegal for anyone other than qualified veterinarian to perform this surgery.
Cats undergoing castration must be fully anesthetized during the procedure because performing surgery without anesthesia is an act of animal cruelty. Try to neuter your cat before he reaches sexual maturity.
