Spay and Neuter Resources

*Greenhill Humane Society’s free spay and neuter surgeries for all feral, stray and free-roaming cats in Lane County (TNR) is temporarily temporarily suspended until further notice. Please check back for updates.*

Greenhill Humane Society’s Veterinary Clinic performs nearly 3,000 surgeries each year!

In addition to spaying and neutering all animals prior to adoption, Greenhill offers free spay and neuter surgeries for all feral, stray and free-roaming cats in Lane County!

Appointments are required and are available Monday, Tuesday and Thursday.

Each cat must be brought in an approved trap, not a kennel, carrier, box, or anything other than an approved trap. One cat per trap. Once you have an appointment for TNR, traps may be borrowed from Greenhill with a deposit. If you have questions regarding the type of traps that can be used for our program, please ask at the time of scheduling.

Call to schedule an appointment BEFORE trapping a cat.

For more information, and to make an appointment, call (541) 689-1503 x140.

About Our Trap Neuter Return Program

In 2006 Greenhill Humane Society implemented the Trap Neuter Return (TNR) program. Gaining popularity nationwide in animal welfare and shelter circles, TNR programs have shown to be the most effective, humane solution to an epidemic of feral cat colony breeding. TNR is a method of humanely trapping feral cats, sterilizing them, and returning them to their colonies to live out their lives. TNR can also involve a colony caretaker who provides food, adequate shelter, and monitors the cats’ health.
