Welcome to a bold science-based project to end the overpopulation of homeless pets by developing Spay and Neuter Cookies.

Once completed, the Cookies will be capable of spaying and neutering – without surgery.

Yes, we’re on track to being able to use food instead of surgery.

The Spay and Neuter Cookies are being designed to be species and gender specific.

Dog cookies will only work on dogs.
Cat cookies will only work on cats.
Spay cookies will only spay females.
Neuter cookies will only neuter males.

Better yet, they are being engineered so that they will only need to be eaten one time.

That’s right. One time.

The ingredients are safe — many of us have eaten them ourselves — and the landmark clinical trials have begun.

This is a large project so we need your support!

You can help by becoming a member and sharing this exciting project with others.

Imagine spaying and neutering homeless pets by simply allowing them to eat a cookie.
