The Million Cat Challenge is a shelter-based campaign to save the lives of one million cats in North America over the next five years. The core strategy of the campaign focuses on five key initiatives that offer every shelter practical choices to reduce euthanasia and increase live outcomes for shelter cats. This life-saving campaign is a joint project of the UC Davis Koret Shelter Medicine Program and the Maddie's® Shelter Medicine Program at the University of Florida, led by Drs. Kate Hurley and Julie Levy.

Maddie's Fund believes the five initiatives of this campaign are important to help save the lives of one million cats.To that end, any brick-and-mortar shelter that takes in cats with adoptions open to the public must be an active participant in the Million Cat Challenge to be able to apply for a grant from Maddie's Fund.

If your organization is not a physical shelter you are exempt from this qualification.(Organizations that are foster-based rescue groups, TNR groups or non-profit veterinary clinics can - and are welcome to - register with Million Cat Challenge as a Supporting Organization, but that is not required for a Maddie's Fund grant.)

Additionally, if your organization handles dogs only, you are exempt from this qualification.
