I think destroying all kill shelters would be a horrible idea. They don't put animals to sleep because they want to, they usually have no choice. No Kill shelters are great, but they are almost always full. Most no kill shelters refuse to accept owner released pets because they just don't have the room. Shelters that do put animals to sleep at least give as many animals as possible the chance at finding a home. While death is a sad option for many of these animals death is much better than a life of hunger, abuse and neglect. If they didn't exsist many animals would live in those horrible conditions because they wouldn't have a place to go. It isn't the shelters fault. It's the people that refuse to spay and nueter their pets and chose not to care for them or their offspring.
