To Jill concerning the tissue samples: Jill - the results of what the ferret had - a tumor in it's spleen and parvo - are not from me. I am hoping to get a look at those slides or samples of tissue. Parvo is an enteric disease of dogs which ferrets cannot contract. A tumor of the spleen is very unlikely in such a young ferret. I would suggest that it is instead the producation of blood cells in the spleen, which we commonly see in young ferrets and is considered a normal finding. I talked with your vet this A.M. and she relayed the results to me. It seems that a M.D. read out these slides instead of a veterinary pathologist, so I would not trust the accuracy of these results. Now we have to work on getting a copy of the slides or blocks for me to get a look at....
