Alley Cat Rescue

Alley Cat Rescue is leading the way in promoting humane care for all cats. ACR is committed to helping stray and outdoor community cats in the United States and around the world through compassionate, nonlethal care to improve cats' lives. ACR works to reduce the number of feral cats living in colonies through a proven method called Trap-Neuter-Return (TNR), and provides support to cat caretakers and cat owners alike through low-cost spay/neuter programs, assisting with behavioral issues to keep cats in homes, and educating the public on the benefits of TNR and how to get involved.
