Re: the recent ADV discussions...I realize a point was made about the actual number of cases probably being larger than we know, but nonetheless, what kind of numbers (known) are we talking about here? I have been wondering just how widespread this is. Also, I'm curious to know what the rate of increase seems to be. Admittedly, I'm also wondering if those numbers would actually represent a true increase, due to factors like more vets now being aware of ADV than before, whereas in the past a ferret with ADV may have been diagnosed instead with any number of other things. How can we find these things out? Shannon Sterling, Pandora, & Jasmin [Posted in FML issue 3852]
