We want to end the overpopulation of feral and homeless cats on the streets of Boston. We trap, neuter (or spay) feral and homeless cats. We coordinate other veterinary care for these cats. We release feral cats and ensure their survival by providing daily care for them in their street homes (known as colonies), including monitoring for health, safety and new arrivals, feeding, providing shelter and other protection from the elements. We evaluate homeless cats for adoptability and foster them. And, although we believe that a program of TNR (Trap, Neuter, Release) is a vital part of ending overpopulation, we provide education to the public about the importance of spay and neuter programs and about the problems faced by homeless cats. We train volunteers to help us with these activities.
