Companion Animal Spay and Neuter Welfare Benefits

Spaying and neutering companion animals prevents suffering from overpopulation and improves individual health outcomes.

Welfare Considerations

Companion animal overpopulation causes enormous preventable suffering — millions of animals are euthanized annually simply because there are not enough homes. Spaying and neutering directly reduces this crisis while also benefiting individual animal health. Spayed females avoid mammary tumors and life-threatening uterine infections. Neutered males have lower rates of roaming, fighting, and certain cancers. Low-cost spay-neuter programs make this accessible for all income levels and are among the highest-impact welfare interventions available.
