This query is mostly for Dr. Williams: A while back, I wrote about my 5yo ferret, Olly, that was losing hair all over and had swollen lymph nodes. My vet suggested that it could be an adrenal gland tumor or lymphosarcoma. He took some fluid samples (not cheap) which were inconclusive (no surprise). The best way to determine the problem is through exploratory surgery. The surgery will cost about $250. With Xmas approaching, this is a bit stiff for me right now. And my husband is not so sure its necessary since it is not obvious that Olly is suffering. His swelling is down, so his back legs no longer fail on slippery surfaces. He seems to get around fine and does not seem overly listless, but certainly doesn't feel well enough for even an occasional ferret dance (but he didn't do that often before he started losing hair). We've obviously been stalling on deciding whether to go ahead with the surgery. (Please try to understand, we love Olly, but our situation right now doesn't make it easy to drop this kind of cash on him - plus my vet can't guarantee that surgery will solve the problem.) During this time (a couple of months) Olly's health has not worsened (as I mentioned, the swelling's reduced). Why? My husband doesn't think that just hair loss should warrant an expensive operation. What will happen if we don't do this soon? (I will quickly have the surgery done and pay in installments if I need to get this done now.) [Posted in FML issue 0631]
