Trap Neuter Vaccinate Release

This Trap-Neuter-Vaccinate-Release (TNVR) Program is a cooperative effort between NHAO, participating local licensed Veterinarians, and the caring citizens of Macon County.

The purpose of the NHAO TNVR Program is to improve the lives of feral cats residing in Macon County by neutering, vaccinating and then releasing them back to their original location, thereby discouraging other feral cat colonies from moving into the territory.

Neutering improves the overall health of all cats. Studies have shown that neutering reduces the incidence of several types of cancer, infection, and serious medical conditions.

Neutering also reduces territorial aggression and disruptive behavior which can cause serious injury and infection.

The secondary purpose of this program is to reduce the feral cat population. A healthy feral female with proper shelter and good nutrition can have more than 180 kittens in her lifetime. Her female kittens will reach sexual maturity at 5 to 6 months and will begin to have their own litters, continuing the cycle. 

All cats that participate in the NHAO TNVR Program will receive rabies and FVRCP (rhinotracheitis, calicivirus, panleukopenia) vaccinations and while under anesthesia have the tip of their left ear removed. Tipping of the ear provides a universal symbol that the cat has already been neutered. 

PARTICIPATION CRITERIA - This program is for true feral cats. Feral cats avoid human contact and do not allow themselves to be handled by humans. Residents that have a feral cat population in their area should contact NHAO by emailing with any available information about the animal. They will be contacted by the TNVR staff as soon as possible.


TNVR is an expensive and time intensive program.. Monetary donations and donations of volunteer time are both appreciated and vitally needed to keep this program continuing indefinitely for the Decatur and Macon County area.
