Charles River Alleycats (CRA) is dedicated to promoting and reducing the number of homeless and feral cats in the greater Boston Area through non-lethal means, by using programs such as trap-neuter-return (TNR). In this way feral cats will be sterilized and returned to their outdoor homes, where caregivers provide ongoing shelter, food and supervision. Adoptable cats that have become lost or abandoned will be placed into homes whenever possible. In cases where CRA can, it will facilitate low cost spay/neuter services to those who are unable to afford this for their pets.
