As Arizona's largest nonprofit spay and neuter clinic, providing care for over 24,000 animals every year, Altered Tails relies on your donations to continue our lifesaving efforts. Your donations allow for the most vulnerable to receive the medical care they need, those suffering difficult times to give their pets the preventative care they deserve, and allow Altered Tails to grow their impact on the lives of animals in the Valley and beyond. Give today and make a better world for animals in your community.
