Allowing a female cat or dog to produce a litter does not have any benefits to the animal. Animals who go through heat cycles and pregnancy are at higher risk for uterine and mammary problems, including mammary cancer, which can be fatal.
There are health risks to the mother during the pregnancy and when giving birth. Proper pre-natal care, emergency care for birth complications, and proper newborn care are expensive and time-consuming.

No. Your pet will actually benefit from spaying or neutering, because he or she will lead a healthier and longer life. Pets become fat and lazy as a result of overeating and a lack of exercise, not from spaying or neutering. Furthermore, spaying a female eliminates the possibility of her developing uterine and/or ovarian cancer and greatly reduces the chance of breast cancer. Neutering a male eliminates the risk of testicular cancer.
