The Animal Defense League of Arizona is a statewide animal protection organization.  Since 1987, it has worked on a variety of campaigns to protect Arizona’s animals. ADLA focuses on a small number of issues at a time to assure that it can have a real impact.  Its current primary issue is pet overpopulation.

Tens of thousands of unwanted animals die in Arizona shelters each year.  ADLA believes that many problems that confront dogs and cats are a result of animal overpopulation. That is why virtually all of our resources for companion animals are devoted to the Spay Neuter Hotline.  The Hotline provides information on spay/neuter resources throughout Arizona - online, by phone and at outreach events in the community.  It makes thousands of referrals to low cost and free services for pet dogs and cats each year.

The Hotline also sterilized 15,000 cats through Trap Neuter Return (TNR) in each of the last four years. It has fixed over 70,000 cats since 2009. Many caregivers cannot afford to donate to help defray the cost of their surgeries. We help them through our financial assistance list.

ADLA's TNR program ensures that more outdoor cats are getting fixed and not reproducing in Maricopa County. ADLA’s efforts and those of other groups in the Fix. Adopt. Save. program are resulting in dramatic decreases in cat euthanasia - it’s down by 78% (comparing the first two quarters of 2012 and 2015).  

If your passion is helping companion animals by spaying and neutering pets and outdoor cats, be assured that your donation will be used to directly help animals in need.  $100 will allow us to fix four cats; staff an outreach table at a health fair in a low income neighborhood; or print 5,000 outreach flyers.

No organization is able to do so much for animals with so little, and that is because we have so many volunteers who generously give their time for animals and leverage the work of our small, but passionate and talented staff.   ADLA is also fortunate to work in a number of coalitions with other great organizations and individuals. Please help us reach our goal to diminish the suffering of animals by reducing dog and cat overpopulation in Arizona.
