By having your pet spayed or neutered, you will do your part to prevent the birth of unwanted animals. What's more, you could be setting your pet up for a longer life, as studies have repeatedly shown that spayed or neutered dogs and cats live longer, on average, than other dogs and cats. This advantage is likely due to the health and behavioral benefits of the procedures.

HEALTH BENEFITS

Established health benefits include protection against some potentially serious diseases. Spaying female dogs and cats can prevent uterine infection and reduce the risk of breast cancer. Neutering males can eliminate their risk of testicular cancer and reduce their risk of developing enlarged prostate glands (known as benign prostatic hyperplasia).

BEHAVIORAL BENEFITS

Behavioral benefits relate directly to the decreases in certain sex hormones that occur after spaying or neutering. Removing a female dog or cat's ovaries eliminates their heat cycles and generally reduces mating-related behaviors that may frustrate owners. Removing a male dog or cat's testicles reduces their breeding instinct, resulting in less roaming and fewer urine-marking behaviors.
