Spaying and neutering reduces the number of unwanted puppies and kittens.
Theoretically, in 7 years, the average female cat and her offspring can produce 42,0000 kittens, and in six years, the average female dog and her offspring can produce 67000 puppies. Spaying and neutering is an easy way to prevent accidental litters.
It also:
-
Reduces problematic behaviors such as mounting, urine spraying/marking, roaming, and male aggression.
-
Spaying eliminates a female’s heat cycle, which can cause a female to cry incessantly, pace, and act nervously. It can also cause an unsightly bloody vaginal discharge in dogs and attract unwanted male visitors.
-
Reduces the risk of some health problems such as mammary tumors in females, and prostate enlargement and prostate cancer in males. A female dog that is spayed before her first heat has about a 99.5% less chance of developing mammary tumors in her lifetime than an intact female.
-
Spaying eliminates the risk of life-threatening uterine infection, and uterine and ovarian cancer in females and neutering eliminates the risk of testicular cancer in males.
- Altered animals tend to be calmer and happier.
