See photos of adoptable pets in Tampa Bay
It's a problem as old as that doggy in the window. The animals with big baby eyes and fluffy tails and snuggly noses trot off into happy homes. But lurking in the shadows are the loners - seniors, animals with medical problems, stigmatized breeds like pit bulls, cranky types who just want to be left alone. In honor of the outcasts, Petfinder.com named this week "Adopt a Less Adoptable Pet Week." We visited some local shelters looking for bruised apples - some old, some sick and chubby, some inexplicably unpopular, all in need of a home. See photos.
