Spay/Neuter & TNR Services

Community Cats

Lane County is home to many “community cats.” These are outdoor, unowned, free-roaming cats. They can be friendly or skittish, young or old, altered or unaltered. They may or may not have a caregiver. These cats can live individually or they might live in colonies. You can learn more by visiting our Outdoor and Community cats page

Services for Community Cats

Greenhill’s TNR (trap – neuter – return) program was started in 2009 to help reduce the overpopulation of community cats.  Since the inception of the program, we have performed an average of 900 TNR surgeries each year.

Due to the high need for this service, Greenhill is prioritizing managed colonies of 20 or more catsIf you are needing spay/neuter for an individual cat or a group of less than 20, contact our Feline Receiving Department at 541-689-1503 x 133.  

The TNR program is not available for any owned cats. 

For assistance with TNR for a colony you are caring for, please follow these steps:

Financial assistance may be available through grant funding and the donations of generous supporters whose gift ensures that this program remains accessible to those unable to cover the full cost of the services. You will be able to indicate the need for financial assistance during the scheduling process.
