There are tens of millions of free-roaming, community cats across the U.S., and many more around the world. Since female cats can have multiple litters of kittens a year, their offspring multiply exponentially. It used to be common practice for communities to catch and euthanize community cats. But that’s not humane, doesn’t stop overpopulation, and isn’t cost effective. Trying to get the cats into shelters and adopted doesn’t work either. There are too many of them, and many prefer the life they have. They may be feral, and they likely have a cat colony “family.” In pet-friendly cities, Trap-Neuter-Return (TNR) programs help community cats live out their lives in their colony, but not breed more unwanted cats. The cats are humanely trapped, spayed/neutered, vaccinated and returned to their home location. Studies have shown the cats stay healthier thanks to vaccination. Plus, mating behaviors like roaming, spraying and fighting stop once a cat has been sterilized.
