I hope I've spelled that right!
Judging by the lack of info on the web, this is a bit of a long shot but I wondered if anyone's had experience, or even heard of, this condition.
A colleague at work has a young cat (under three years old, I think) who has developed it. The vet has done an autopsy and she'll get the result later this week, but it sounds really bad. Apparently it's very rare, and even rarer in cats over a year old.
