WaHi Cats, a 501(c)(3) nonprofit dedicated to TNR in northern Manhattan, closed permanently on Dec. 31, 2024. Thank you for 16 wonderful years. Washington Heights Cat Colony is a non-profit TNR (trap-neuter-return) group located in upper Manhattan. We are dedicated to humanely reducing the local feral cat population by using the TNR method; to educating the surrounding community about the benefits of TNR programs; to placing adoptable cats and kittens from colonies in homes where possible; and to maintaining the health and well-being of our neighborhood feral cat colonies by providing ongoing care (food, water, shelter, and medical treatment) for the feral, stray, and abandoned cats in our community.
