Low Cost & Free Spay/Neuter

Spay/neuter is the most important step we can take to address a nationwide problem of overpopulation and help reduce the number of animals in the shelter.

Spay and neuter services are available by appointment only.

Please call the Key West office at 305-294-4857, or the Marathon office at 305-743-4800 for more information.


We offer free spay/neuter surgeries for feral cats through our Trap-Neuter-Return program.

Community members between mile markers 0 and 70 are eligible to have feral cats spayed and neutered through our Trap-Neuter-Release (TNR) clinic at no cost. TNR services are available by appointment only. To schedule a TNR appointment, the trapper must come to the Florida Keys SPCA during office hours to fill out paperwork and discuss available TNR slots. Trapper should be prepared to humanely house the trapped cat overnight before surgery in a warm and enclosed area. Feral cats CANNOT be dropped off and held at the shelter before surgery day.

Humane traps are available for rental at the shelter for up to 2 weeks. To rent a trap, a refundable $75 deposit is required.  

On the day of your TNR appointment, check in time will be between 8:30 and 10:00am. Things to keep in mind before check-in:

*Cats MUST arrive in a secure trap with newspaper.

*Water and food should be removed from the trap before check-in, if possible.

*Cats will be altered, given a rabies vaccination, and a notch in their right ear.

*Trappers will be notified when surgery is complete and cat is ready to be picked up. Cat must be picked up the same day as surgery and cannot stay at the shelter overnight.
