If you're out and about in any community in America, eventually, you'll see a cat missing part of its left ear. An "ear tip cat" is one that has been spayed or neutered in a trap-neuter-return (TNR) program. This is a management strategy for stray cats.
Feral cats are typically unapproachable by people. They can admittedly be a nuisance in certain areas. Some people advocate for relocation as the best way to deal with these animals, but is it really the best option?
TNR is the process of trapping feral cats, having them neutered and vaccinated, and then returning them to their colonies so they can live out their lives there. It's a proven method for managing feral cat populations that also reduces the number of unwanted kittens born each year. TNR cats live healthy lives and defend their territory from other free roaming cats. It's a win-win for everyone.
