The single most important thing that we can do to save cats and dogs from all the suffering and death that their overpopulation causes is to spay and neuter them. Spaying and neutering are routine, affordable surgeries that can prevent thousands of animals from being born, only to suffer and struggle to survive on the streets, be abused by cruel or neglectful people, or be euthanized in animal shelters for lack of a loving home.
Spaying and neutering makes a big difference: Just one unaltered female dog and her offspring can produce 67,000 puppies in only six years. In seven years, one female cat and her offspring can produce an incredible 370,000 kittens!
Sterilized animals live longer, happier lives. Spaying eliminates the stress and discomfort that females endure during heat periods, eliminates the risk of uterine cancer, and greatly reduces the risk of mammary cancer. Neutering makes males far less likely to roam or fight, prevents testicular cancer, and reduces the risk of prostate cancer. Altered animals are less likely to contract deadly, contagious diseases, such as feline AIDS and feline leukemia, that are spread through bodily fluids.
