Spay-Neuter Services of Indiana provides spay & neuter assistance.

SNSI helps Hoosiers get them fixed by providing low-cost surgery certificates to limited-income individuals and free surgery certificates to 501(c)(3) non-profit animal welfare groups and municipal shelters. A statewide network of veterinarians graciously discount their services for our clients, and SNSI pays the remaining cost. Since our inception in 1977, we have helped spay/neuter more than 110,000 pets.

In addition to providing direct services, SNSI also works to provide information regarding resources in your area. Learn more by visiting our Indiana Animal Resources by County and the Indy Pet Resource Flyer.
