The answer to this question depends on you and your family. It may also vary from one animal shelter or rescue group to another. Here are some principles that can guide you:
A female cat has a very short “reproductive” life span, just about two years—even if spayed during her first heat cycle after she comes into season (see box). Unless the feline is sterilized before her first estrus (heat) cycle, she will go through it again and again over the course of her life. Each time she goes into estrus, she puts herself in danger by exposing other cats in the vicinity to infection with deadly herpes virus. And because male cats have no way of knowing when their females are or aren’t pregnant, they’re quite likely to get them pregnant! Spaying does not eliminate all chances for pregnancy—but it’s an important step toward eliminating them!
How does spaying affect my pet? The surgery itself doesn’t hurt much at all; anesthesia makes most pets pretty sleepy afterward. If you are considering having your pet spayed or neutered, please remember that the procedure has benefits well beyond preventing unwanted litters early in life. The surgery greatly reduces many cancers later in life as well as helping prevent osteosarcoma (bone cancer) while trimming down extra fat tissue around internal organs which increases pressure on those organs without providing any additional padding therefor decreasing risk of heart disease and liver problems later in life for both males
