If you actually care about animals dying in kill shelters the solutions are to open more shelters, do more to stop abusive conditions for animals before they get out of hand, and most importantly stop breeding animals. Animals are killed either because shelters don't want to take them in do to their condition or they are too full. You can blame the no kill shelters as well, because they don't take in every animal. But they aren't really to blame either, people who support the industries that breed pets are.
