I was also torn on doing my SamSams Spay. I waited just over 3 years, she is 10 now. But after a discussion with my Vet on the medical risks of non spay. (uterin cancers and such) The higher death rates of non spay. The death from overpopulation, starvation, kill shelters, etc. with millions of kittens per day in this world. Please consider doing it. The benefits are 10 to one.
