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 and help is needed.

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.

In 1980 Alex Pacheco 
also fathered The Silver Spring Monkey Case by working undercover in a federally funded animal research facility in Silver Spring, Maryland, less than 10 miles from the White House.

Gathering evidence of cruelty to animals, he compelled the District Attorney’s Office to take legal action, with Pacheco leading law enforcement agents into the laboratory, carrying out the world’s first and only police raid on an animal laboratory.

A Silver Spring Monkey

Unprecedented, the raid was soon covered on the front pages of every major newspaper from the Wall Street Journal and the New York Times, to the Soviet Union’s largest newspaper Tass, including coverage by every U.S. television network.

Broadcasting photographs taken by Pacheco, documenting severely mutilated laboratory primates, the case sent shock waves through the biomedical community worldwide.



Two of the Silver Spring Monkeys

Known as The Silver Spring Monkeys Case, it generated a political and social battle that was fought in Congress, the courts and in the streets – with Pacheco spearheading a 15 year campaign against the laboratory’s funding agency, the National Institutes of Health, over the fate of the laboratory primates.

Oliver Stone

Film director Oliver Stone wrote a forward to the book Monkey Business, the Disturbing Case that Launched the Animal Rights Movement, in which Stone wrote “The political campaign to save the Silver Spring Monkeys gave birth to the Animal Rights Movement in the United States.”

As co-founder of both the world’s largest animal rights organization (PETA) and the world’s largest nonprofit animal adoption service (Adopt A Pet), Pacheco’s 30 year track record of victories for animals is arguably unequaled.

Though less widely known than PETA, it’s likely that Adopt A Pet is responsible for the adoption of more animals than any other nonprofit in the world.  Adopt A Pet provides free services to over 12,000 humane societies and animal rescue organizations by using it’s website to host over 100,000 adoptable animals nationwide, with over 30 million website visitors annually.   Read more
