To neuter your male cat is to have his testicles removed. The result of both operations is that your pet will no longer be able to bring more homeless animals into the world. That's significant indeed when you consider the fact that more than four million dogs and cats have to be humanely destroyed each year for lack of good homes. Spaying and neutering are also better for your pet. Spaying eliminates the possibility of uterine or ovarian cancer and greatly reduces the incidence of breast cancer, particularly when your cat is spayed before her first estrous cycle.
Neutering reduces the incidence of prostate cancer and prostate disorders.
Neutered cats are also less likely to spray and mark territory, and spayed cats will no longer go through annoying heat cycles. To top it all off, in addition to living longer, healthier lives, cats who are spayed or neutered make better, more affectionate companions. But both procedures offer a lifetime of benefits. When it comes right down to it, if you can't afford to have your cat spayed or neutered, then you can't afford to have a cat. No matter how careful cat owners are, there's always the chance their companion may slip out the door and become lost.
