Flatbush Cats, a non-profit organization, is tackling the issue of overcrowded animal shelters in New York City. They aim to reduce the burden on these shelters by providing assistance through their TNR (trap-neuter-return) program. The organization's dedicated team traps stray cats, gets them neutered and vaccinated, and then returns them to their original location or finds them suitable homes. By doing so, they contribute to controlling the population of stray cats while ensuring their well-being.
