There are long-term health benefits to your pet when it is spayed or neutered-it can lower the risk of several cancers and diseases. Ask your veterinarian to explain these benefits. Obviously, the primary benefit is controlling the pet population by regulating the number of unwanted pets. Spaying and neutering requires surgery, and surgery requires anesthesia.
The cost of spaying and neutering procedures includes the anesthesia, the veterinary team’s time and knowledge, surgical equipment and other medicine, hospitalization, etc. A litter of unwanted puppies or kittens will certainly outweigh the cost of having your pet spayed or neutered early on.
