What is TNR?

Trap-Neuter-Return, or TNR, is cornerstone of Colony Management and the only successful long term strategy for humanely controlling the population of feral or free roaming cats.  A sterilized colony of feral cats will stabilize, and eventually decline in numbers through illness, accidents and old age.  A sterilized colony often act to keep new, unsterilized cats away from their colony.

If you want to reduce the amount of free-roaming cats in your neighborhood, the solution is to maintain a neutered, managed colony. Trap-and-kill programs do not work. Because of the territorial nature of feral cats, when all the resident cats are removed from an area a “vacuum” is created, and un-neutered cats from nearby neighborhoods will move into this new unclaimed territory. The cities of Berkeley and Oakland endorse the use of TNR to control the population of free-roaming cats in their jurisdictions.
