Just read about this site, they list dogs in shelters (also post photos), who are on doggie death row, and how many days they have left. Depressing to read, but many dogs have thankfully been saved by dogsindanger.com.
I just can't look...I don't even think I'll be able to go to the shelter and choose a new cat when the time comes because here in FL they get 3 days and I'd leave with all of them. I might have to just send my husband to make the choice (of course, he'd probably come home with all of them too). I remember once a humane society wanted to show a commercial that showed a cute kitten in front of a pile of dead cats and dogs, and it was banned. I don't think it should have been because that's the reality...it might make people think before breeding.
