I have experienced the "hard to wake" syndrom in several ferrets. It is very common in younger ferrets, but I have seen it in older ones as well. I could be wrong here, since I'm not a vet, but I think someone is feeding you a line of bull about them going into an actual coma. I think it's just more ferret stubborness that keeps them from waking up until they are ready. I have read about this in a ferret book, also, and it claimed this is normal. All of my ferrets have always awoken eventually, and never shown any ill-effects from this. -- M. Todd Hess [Posted in FML issue 0824]
