Spaying and neutering refer to the surgical sterilization of an animal. In other words, spaying and neutering ensures that your pet cannot reproduce.
Pets are typically spayed or neutered when they are 4-6 months old although the procedure can be done from as early as 8 weeks old through to adulthood. It is best to have this surgery done before your pet reaches sexual maturity. Females should be spayed before their first heat. Some vets will also perform pediatric spay/neuter. Please consult with your vet.
Even if your pet has a litter and you find homes for all of them, each of those pets takes a potential home away from other homeless pets waiting in a shelter or rescue. But aside from this responsibility, there are also significant health benefits for your pet.
