600 Million Dogs is on a mission to end the leading cause of suffering for dogs and cats - overpopulation. We’ve been working tirelessly to develop the Spay and Neuter Cookie, which will spay and neuter dogs and cats safely and effectively in one dose. We believe it's possible to create this cookie and that it could potentially solve the stray dog and cat overpopulation crisis forever. But we need your help to make the Spay and Neuter Cookie a reality. Please consider funding the development of the Cookie by visiting 600milliondogs.org/donate and donating today. Together, we can make history for the animals!
