Hi everyone. I have had a ferret for about three months now (a male, approximately 2-3 yrs old). Lately he has been very active, moreso than usual, and not sleeping much at all. I make sure he gets plenty of play time, at least 3 hours a day (usually closer to 5 or 6 hrs). When he is in his cage, he will scratch constantly on the door (last night this went on for 2 hours, non-stop). I was hoping someone could tell me what this could mean (illness, stress, etc.), and if there's anything I can do to stop it. Thanks for your help, in advance. [JH] [Posted in FML issue 3295]
