Actually, I didn't mention it, but I think Linus the Eldest *has* had ECE. A couple months after I first got him (he was 1 1/2 yrs old), he got really really sick. He didn't get "green stools" necessarily but they were quite watery and off-color. He slept, did nothing else. For almost 2 weeks. I had to force feed him food, fluids, and antibiotics literally every 3 hours (not the antibiotics, obviously). I kept him separate from my other two, but of course only after he showed signs of sickness so he got the other 2 sick. He got better but had another relapse. All told, I think it was 6 weeks of my nursing the 3 of them constantly (I even took them to work with me), but they did get better. Now, years and years later, Linus has IBD, and his roomie Zooey was also diagnosed with IBD. The 3rd ferret, Elsa, she got really really sick when she was about 3 and died. Possibly lymphoma, it happened pretty fast, and her decline was fairly steady. but also, I thought you could test for ADV? Towards the end of Zooey's life they suggested her problems might have been complicated by ADV, but she died before we could do a test. We haven't gotten to that stage with Linus yet.
