I completely agree. Sterling and Pandora, who used to really pounce on and wrestle with Jasmin, have taken to playing with him very gently over the past month or so. I didn't know why until he got somewhat bad and I took him to the vet last week, only to find out he has insulinoma. What amazes me is that I've been told that lots of physical activity will aggravate insulinoma, lowering glucose levels even further; somehow the ferrets knew he was sick before we did, AND they somehow knew to play gently with him. They are very intuitive, truly amazing animals. Shannon Sterling, Pandora, & Jasmin [Posted in FML issue 3923]
