Recently I've noticed one of our ferret's behavior has changed. Its hard to put into words. He is more interested in what what we are doing. When he is in the cage (and awake) and we are around he is actively going back and forth in the cage wanting to get out. During playtime he bounces and dances and plays on his own but he spends a lot of time at the gate to the rest of the house. Our ferrets have 1 and 1/2 rooms plus the hall between them for a play area. He lays down at the gate to the rest of the house. Even if I am in the ferret room sitting and playing with the rest of our 8 ferrets. He'll come into the room and loop around the room go through a tunnel and back to the doorway. His history is he was purchased from a breeder at 3 years of age (mis-treated at that breeder for all of those 3 years). He was fixed and not desented. He was a bad bitter and it took 7 months of love and patients and lots of bandaids but now he is the sweetest ferret you could ever have. We have had him for 2 years and 9 months. He had adrenal disease and surgery to remove his left adrenal gland, then it came right back. He now has a deslorin implant (2 months ago). He is about 6 years old. He would still dance and bounce when during playtime. There was a period of about 2 - 3 months where he didn't bounce and he seemed to sleep more. We were planning to have his glucose tested soon but then he changed his behavior, not he bounces and dances and looks happy and energenic he seems to have lost 3 ounces of weight (we have ECE in one or two of our ferrets so we don't know if he now has it or not, we're watching that as well) His fur is still kind of thin and a little course. I know it's odd to worry about increased activity or interest in us but to go from bouncy and a some interest in us (play) to less active and sleeping more to the point where insulinoma is suspected then back to bouncy and a lot of interest in us, makes me wonder if something is going on. I also know that some ferrets go through stages as they learn that they are in a forever home and not a temporary home and maybe he has just crossed one of those stages. He is deaf or mostly deaf (we think he can hear some things). Am just worring too much? I sit at my computer which is about 25 - 30 feet away from his cage and sometime I can see him just sitting there watching me. Thank you Mike [Posted in FML 6683]
