Actually, I think it is good because it is an eye opener to people who get rid of their animals for stupid reasons. Not all of them are stupid (for example..allergy reasons) but there are people out there who might be ready for an animal and want to save and animal who is about to lose it's life. I work for a rescue, a no-kill shelter, but I would rather see someone adopt a dog who is about to get euthenized than from the no-kill shelter. If I could adopt another dog then I would definitely go to that website and see which dogs needed to be adopted.
I know all the animals in the world (or even on that website) can't be saved but even if a few of them can, it would be worth it.
I think education is the key..education about spaying/neutering pets, being ready for an animal before going out to adopt one, etc. That is why some of those animals are in that predicament...because some people just don't take pets as serious and think they can throw them away like trash or breed them like crazy and then don't know what to do with the litter so they give them to animal control or whatever.
If people don't want to look at the website then they shouldn't go there. But I think they are targeting people who want to save pets' lives. Some people go to those types of shelters to adopt those animals and foster them until they find a good home for them. I think those people are good samaritans (as long as they don't hoard them...then that runs along the line of just being crazy and perhaps just as bad as puppy mills).
So overall, I don't think it is wrong.
