Female British Shorthair cats can be neutered when they are 6 months old, and the best time for neutering is until the age of four. The earlier the cat is neutered, the better. After sterilization, the female cat will be prevented from going into estrus and there will be no trouble with uterine diseases, so the cat can grow up healthily. However, the breeder needs careful care for a period of time after sterilization. For 15 days after sterilization, the cat's wounds must be cleaned every day to promote wound healing and avoid infection.
