My 2 year old ferret, Cassidy, sleeps all the time!  He has always been this
way.  I can even hold him in the air and he won't wake up.  He probably
sleeps about 75% of the time and sometimes appears to be dead.  Is this
normal?  His appetite is fine and doesn't seem to be sick as far as I can
tell.
