Founded in 1990, Alley Cat Allies’ mission is to end the killing of cats and to lead the movement for humane methods of care for outdoor cats, including accessible, low-cost spay and neuter services for all cats. Institutional killing in animal control pounds and shelters is the leading documented cause of death for cats in the United States. Alley Cat Allies seeks wholesale reform of the animal control and sheltering system.

To fulfill its mission, Alley Cat Allies:

  • Advocates for pounds and shelters to keep public records of animal intake and kill rates, for public and mandatory government oversight, and for increased pound and shelter accountability;
  • Mobilizes and educates the public and leads the national movement to end the killing of cats and to protect and improve their lives;
  • Supports the efforts of, and acts as the national voice for, thousands of individuals and groups across the U.S. who provide humane care for stray and feral cats. 

Alley Cat Allies is the premier national advocate for stray and feral cats, and the world’s authority on Trap-Neuter-Return, a humane method of care for feral cats. Trap-Neuter-Return improves cats’ lives by ending the breeding cycle, and creates a safety net for the cats and the community.

Outdoor cats thrive in virtually every community, and Bethesda, Maryland-based Alley Cat Allies consults with animal control facilities, shelters, and concerned citizens across the nation and around the world to help develop and implement municipal Trap-Neuter-Return programs and expand the accessibility of spay and neuter services. Alley Cat Allies was instrumental in changing policies on feral cats in Washington, DC, Baltimore, and many other cites, and is a founding partner of the National Capital Area Spay and Neuter Center, a regional low-cost, high-volume clinic that spays and neuters Washington, DC feral cats at no cost.

Alley Cat Allies reaches more than 600,000 organizations and individuals through its education and outreach programs including: brochures, factsheets, videos, and educational materials as well as two newsletters – Alley Cat Action and Feral Cat Activist – and its extensive web site,  The organization holds conferences and workshops across the country to provide continuing education on feral cat issues and to advocate for changes in our animal control and sheltering system.

Alley Cat Allies created and maintains the Feral Friends Network, a group of over 1,800 seasoned caregivers and veterinary professionals worldwide who volunteer their knowledge and experience to assist caregivers and educate neighbors and communities locally about feral cat, Trap-Neuter-Return, and low-cost, high-volume spay and neuter programs.

A 501(c)(3) nonprofit organization, Alley Cat Allies has more than 170,000 supporters nationwide and throughout the world.
