What is Arizona Animal Welfare League and SPCA AAWL / SPCA is Arizona's oldest and largest no-kill shelter. We provide adoption, resource and education programs that improve the quality of life for dogs and cats and offer support for pet guardians. Our shelter facilities are a temporary home for increasing numbers of dogs and cats every year, providing quality care, including medical and emotional treatment for those in need. In 2005, our matchmaking efforts placed nearly 2, 400 pets in new homes with families who love and care for them. Every shelter animal has an enriched environment. For dogs, that includes daily walks, toys, social interaction with other dogs, and play time with people. We have outdoor play yards for dog exercise, play, socialization, and training. Cats have toys to chase, places to hide, towers to climb, and ample attention from loving humans.
