To Tanya, whose Orville is about to be neutered: Tanya - Neutring of a male ferret is not a very big deal. Orville will be up and around in a day. I would go ahead and get it done, and then you'll have over three weeks for everything to heal before you start your vacation. Actually, it's not all that stressful and surgery and is very well tolerated.(Actually, ferrets seem to tolerate most surgeries far better than dogs or cats). Concerning a CBC at less than one year of age - I guess you already know my opinion, but Dr. Weiss is out of town until the weekend...I hope he will give his thoughts on the matter. I think that in the absence of any signs of disease, a CBC is not necessary in animals of Orville's age. It generally provides little information, and will cost you an additional 20-30 dollars. Plus, the animal has to be sedated, or at least restrained, so there is a lot of stress involved. Since Orville will be anesthetized for the neutering anyway, you might consider it, but I definitely would not push it as part of a routine visit for a young ferret. Plus, I am definitively of the opinion that you can't diagnose the presence of tumors from a CBC. That is an inaccuracy that has been floating around for some time now. Several practitioners have said that lymphosarcoma can be diagnosed on the basis of an elevated lymphocyte count, but no concrete evidence has ever been offered. In fact, I have seen ferrets placed on chemotherapy simply on the basis of an elevated lymphocyte count. In domestic animals, by far, the most common cause of elevated lymphocytes in the blood is a chronic infection. Ferrets commonly have chronic Helicobacter infections, which is much more likely a cause of "peripheral lymphocytosis" than lymphosarcoma.
