I tried getting my foster kittens on their website to get them to forever homes. They make you jump through hoops just to qualify to get on their website. We found these kittens on the roadside in near death condition. We paid for their vet care out of pocket, and got them nursed to perfect health after several hundred dollars of vet care.
We hoped to get them adopted, but Petfinder insists on letterhead vet reference letters which our vet doesn't have. Our Google adoption application form just wouldn't suffice for Petfinder. They add layers of onerous requirements that make it impossible to work with them.
Obviously they aren't in the business of finding forever homes. They're just another lousy "non-profit " that doesn't function to help foster pets. I'll stand in front of Petsmart instead.
