This document discusses Trap-Neuter-Return (TNR) programs for street cats. It explains that TNR involves trapping feral cats, getting them spayed/neutered, and then returning them to their outdoor homes. The goals are to reduce the population of homeless cats humanely over time and prevent future litters of kittens from being born into the streets. The document provides an example of a TNR program in the author's hometown that has neutered over 75,000 street cats since 1995. It also describes plans to start the first official TNR program in Nanjing, China at a Buddhist temple that cares for about 25-30 cats on its grounds.
