yes in America it is more like approx 80% 'kill' shelters compared to the approx 80% 'no-kill' shelters we have over here.
..and some of the methods of euthanasia are shocking. there is footage out there of cats/dogs in gas chambers, i haven't seen it and my imagined version is bad enough.
regarding the FB pages, they do result in animals being 'pulled' - taken from death lists and put in no-kill rescues or foster homes. before this and the internet in general all those on the death list just went off to be killed without anyone knowing.
