I absolutely agree about "free to good home". I was just concerned about your use of the term "borderline retarded ". The term utilized now is intellectually challenged. I hate to sound picky or even pc but I am active in a disability rights organization and while we have changed so much in society, it seems we have a way to go with altering the ideas people have abnout the diabled, especially people with mental challenges.
For the record, I know a young woman who has an intellectual disability and she cares for her dog better than most people I know! And she'd never give away free kittens.
