Thank you for visiting SNSI's website.

Spay-Neuter Services of Indiana, Inc. (SNSI) is a 501(c)(3) non-profit organization. SNSI provides financial assistance for spay/neuter surgeries statewide to low-income individuals. Since our inception in 1977, we have helped nearly 70,000 families spay or neuter their pets.

SNSI networks with veterinarians and low-cost clinics to provide affordable spay/neuter surgery options. These veterinarians graciously discount their services to help us further our mission of eliminating the killing of healthy and treatable cats and dogs.
