Val, I know what you mean. I torture myself with Petfinder, too! I keep saying that if I win the lottery, I will get a huge house in the mountains and have loads of kitties (and a maid to clean the litterboxes!
I recommend petfinder to anyone I know who is looking for a pet. With 11 cats, I am just about at my limit (Although if one wandered along who needed a home, I doubt we could/would say no), but I still cruise the website and end up teary eyed at all those gorgeous kitties who need homes.
