The HART low-cost Spay/Neuter Clinic opened to the public in November 2009. The Clinic is located in McHenry Plaza and represents a key aspect of HART's effort to reduce the number of unwanted animals in the region.

The HART Spay/Neuter Clinic provides low-cost spay and neuter services to the pets of individuals whose income level would otherwise prevent them from spaying or neutering their pets. Further assistance can be obtained through the spay/neuter programs of the other animal organizations, depending on the owner's ability to pay. In addition, HART works with other regional rescue groups to spay and neuter their animals prior to adoption.
