I know that Tree House is very small and seem to take only really helpless cases. If you're in Chicago, I think that the Anti-Cruelty Society on Lasalle & Grand is a really great place. I got all 3 of my kitties there. They screen adopters carefully and place animals quickly into good homes. Everytime I've gone, even when I come back the next day, I don't recognize any of the cats. They are for sure no kill, I know one of the vets pretty well.
