Feral Cat / Trap-Neuter-Return (TNR) Resources

What is TNR?

Trap-Neuter-Return (TNR) is the practice of trapping feral cats (cats that are acclimated to the outdoors, unused to human contact, and not suited to be pets), taking them to a veterinarian or clinic for spaying/neutering, and returning them to their original location. Ideally, this should be a permanent "cat colony" that is monitored and managed by humans experienced in caring for feral cats.

TNR projects large and small require planning and preparation.  In addition to securing humane traps (traps designed not to harm the animal) and other supplies, you will need to arrange veterinary care for the trapped cats beforehand, as well as a location for cats to recuperate after their surgery.  You also must ensure that the location where you will be returning the cats is safe, and that you are complying with local laws and regulations.  Use the FixFinder database to locate TNR organizations and TNR-friendly, low-cost spay/neuter services in your area. 


The following resources will aid you in planning a TNR project -- whether you are planning to trap a single cat or an entire feral cat colony.
