A one hour guarantee? That's not a guarantee! What does that tell you about the breeders business ethics. I would definately make a post on the BOI about this person. It's unacceptable that someone would sell you those poor little things in their condition and expect to just get away with it. A little thin is one thing, but skin and bones is quite another. I agree that they might even deserve a visit from animal services to check out their breeding operation, because it scares me to think what the other animals they have look like.
Best of luck raising them, I really really hope they do ok.
