Dr. Julie Levy is the Fran Marino Distinguished Professor of Shelter Medicine Education at the University of Florida, where she focuses on the health and welfare of animals in shelters, feline infectious diseases, and humane alternatives for cat population control. She founded Operation Catnip, a nonprofit university-based community cat trap-neuter-return program that has spayed, neutered, and vaccinated more than 70,000 cats in Gainesville since 1998. In 2008, she joined Dr. Cynda Crawford to found Maddie’s Shelter Medicine Program at the College of Veterinary Medicine, an educational and discovery initiative with a global impact on the care of homeless animals. In 2014, she joined Dr. Kate Hurley to launch the Million Cat Challenge, a shelter-based campaign that saved more than 3.5 million cats in shelters across North America. In 2022, she helped launch Maddie’s Million Pet Challenge to create transformative “communities of practice” that deliver access to care through humane, community-centric programming—inside and outside of the shelter—to achieve the right outcome for every pet.
