On February 7 and 8, 2007, I placed a lot of information about research into chemical or biological sterilization efforts around the world. Take a look at them.
At that Time, Judith Levy felt that $10,000,000 might clinch the deal of finding non-surgical and permanent chemical or biological sterilization of dogs and cats. This would be especially welcome to the world of feral cats and dogs, not only here, but around the world where they do mass "cullings" of dogs, rabbits and cats in often extremely brutal.
Gary may be opening that door.
I suggest FAF open a way for the public to help fund this research. I'll donate.
Found Animal Friends Website:
This gives all the contact numbers and grant/prize info.
Gary, we love you. This is what we need, fundamental research and science.
