Be extremely careful when handling the rest of your collection if the new BP is showing symptoms like this. The 'star gazing' can be an indicator of IBD, but unfortunately the only real test to see if it really is IBD is to send tissue samples off to a lab after the animal has passed. I'm sorry that I don't have any other info for you on encephalothopy. I'll rummage through my books to see if I can find anything on that specific topic for you.
