Humane Animal Partners provides low cost spay and neuter services in New Castle County, DE. Spaying and neutering helps keep the population of cats and dogs more manageable to ensure fewer animals are left homeless. We believe in spaying and neutering (also known as “fixing”) as a moral imperative. Millions of cats and dogs are euthanized each year because there are not enough homes for all of them. You can be an important part of the solution and help your pet live a happier, healthier, and longer life!

Financial Assistance for Spay/Neuter Pet Owners

Although our clinic offers affordable surgery rates, we recognize that some pet owners lack the financial means to have their pets spayed/neutered. There is assistance available through the State of Delaware’s Low Cost Spay/Neuter Program for residents that are currently receiving financial assistance such as Medicaid, Food Stamps, WIC, Social Security Disability and other programs. Qualifying Delaware residents can apply through the State’s website and receive a spay/neuter certificate for only $20. The certificate must be presented at your appointment and will cover the cost of the spay/neuter and applicable rabies vaccine.
