Troy Lynn - First I want to thanks you for the wonderful picture and the ferret treats. While the ferrets haven't tried the treats, yet, I have placed the picture on my desk in full view of everyone that walks it. It is a wonderful attention gettter, and allows me to talk to a lot of visitors to the office about ferrets. I admit to a little white lie - I'm calling it a black-eyed white instead of a weasel - but the people who I'm talking to wouldn't know the difference, and cute is cute. If they think it's a ferret, all the better for ferrets..... Concerning Bonnie - lymphosarcoma is a consideration, but I've yet to see one in a young animal invade the spinal cord. I think trauma is a better possibility, or perhaps a congenital spinal problem. A bacterial meningitis affecting the spinal cord should also be considered - bacterial infections may cause splenic enlargment. My experience with ferrets with juvenile lymphosarcoma is that it often hits the intestine first, resulting in severe diarrhea. A fine-needle aspirate of the spleen would help, and wouldn't require any more anesthesia than you would take for a blood test. Juvenile lymphosarcoma, if that is what we are dealing with, unfortunately, has a poor prognosis and is rapidly progressive. I'm sorry that this is happening to you, especially with someone else's animal while they are away. Keep me posted, and if you can get a splenic aspirate - I'd like to take a look... Thanks again for the great gifts (I feel guilty). BTW, I ho\ave shown "Tragedy of Ignorance" to several people now, and no one has not been touched. It's a wonderful articel, and I keep a copy handy on my desk at all times.... Bruce [Posted in FML issue 1049]
