Neutering male cats can reduce diseases of the cats’ reproductive organs, bring them closer to their owners, and prevent random urination; sterilizing female cats can reduce uterine diseases and keep cats away from irritability during estrus. Breeders who do not want their cats to mate can have their cats sterilized, which can avoid the occurrence of many diseases, stabilize the cat's mood, and extend the cat's lifespan. In addition, cats’ personalities will become more docile after being neutered.
