Spaying and neutering helps reverse the tragedy of pet overpopulation, reduces your pet's chances of developing deadly, costly medical problems, and improves your pet's behavior. Of the more than 30 million puppies and kittens born in the U.S. each year, only one in 10 finds a permanent home, according to the American Humane Association. The rest die of cruelty, starvation, disease, poisoning, or accidents, or they end up in a shelter. Sterilization of companion animals is the key to reducing this tragedy.
Neutered pets are less likely to mark furniture and rugs with urine.
Spayed females will not have heat cycles that soil rugs and furniture and usually shed less fur. Neutered pets can't develop testicular tumors, the second most common malignancy in males, and have a lower incidence of prostate cancer, which is better for your pet and means lower medical bills. Spayed females typically stay healthier and live longer. They have a lower incidence of mammary tumors and no uterine or ovarian cancers, which is better for your pet and means lower medical bills. Sterilization does not change the pet's personality or cause weight gain.
