I need some medical advice from those of you with experience and of course our resident vets. I have a 2.5 year old MF male ferret. He's been passing EXTREMELY dark urine that is the color of coke and very cloudy. Well, I took him and a urine sample to the vet. She says that there are red and white blood cells, so it looks like an infection. She put him on Clavamox for 1 week and NO change. We took another sample of urine and found the same with bacteria. We changed antibiotics to Tribrissen (no side effects at all - and you can be sure I was watching with an eagle eye :-) ). That was last week and still no change. She says the next step is to inject some dye and do some x-rays to see if there are tumors or something going on inside. During all this Ronnie has been very active, eating, playing just like normal. Has anyone ever seen this type of situation and can give me some advice. To Troy Lynn (I think): You posted a few issues back saying you had one ferret that had Insulinoma but had it controlled by diet only. One of my kids has recently been diagnosed with Insulinoma (no seizures or anything, just a low blood glucose after a 4 hour fast) and I want to help keep her controlled without resorting to drugs. Can you advise me on your diet for your ferret? Thanks in advance to everyone. Jennifer & Ronnie (Mom I will NOT PEE in a cup AGAIN!!!!) [Posted in FML issue 1299]
