No, there is no advantage to letting your pet have one litter. However, there are plenty of advantages to having your pet
spayed or neutered! These advantages include decreasing the chances of breast tumors, cystic ovaries, and uterine infections later in life. Spaying (or neutering) your pet also keeps them safer as it decreases their desire to roam, prevents spraying and marking behaviors, and can decrease the risk of prostate cancer in males. In addition, you are helping control the tragic results of pet overpopulation.
