The Full Form of TNR is Trap–neuter–return.

Trap-Neuter-Return (TNR), the humane approach to addressing community cat populations, works. It saves cats’ lives and is effective. TNR improves the lives of cats, addresses community concerns, reduces complaints about cats, and stops the breeding cycle. TNR improves the co-existence between outdoor cats and humans in our shared environment. This is why so many cities are adopting it.

Scientific studies and communities with TNR programs are proof that TNR reduces and stabilizes populations of community cats. Alley Cat Allies was formed in 1990 to bring TNR—which was already successful in the UK—to the U.S. We launched a national movement with our educational materials, regional workshops, mobilization of advocates, and re-writing of laws.  As a result of this hard work,  TNR has become mainstream.
