Hope Champ makes it.
I know about those hidden dangers. Even though it was not in his cage i almost had something similar happen a couple of weeks ago. I was letting Monty Joe do what he wanted while I was holding him on the couch. He stretched out off my arm and was creeping up along the base of the wall and my daughters bedroom door. After a while he seemed to just stay in one spot and my daughter looked over and screemed "He's stuck"! I looked up and he had hooked himself through one of those Latch Hook's to keep little ones out of the bedroom. Good thing all I had to do was lift the hook up and out or I and he would have been in trouble. It was fairly tight, but was able to lift the hook up and release him. It's amazing what little things can turn into a potential hazzard for out BP's.
Again, Hope everything turns out for the good Thump.
