Consider this my formal apology to you on the tone of my e-mail. I wrote a post in a way that is not my usual style. I can only think that I was in a bad mood that day, but there is still no excuse for how I put things... I am an adult after all, so again, my apologies. As for Coonsie urine, I would recommend that you collect a variety of samples, taken at different times of day, and on different days and have your vet look at them more closely. If you can get him to pee directly into a bottle to make it as uncontaminated as possible, that would be best. It may offer a clue as to what is going on, and to see if it is a consistent thing. Antibiotics certainly do have an affect on the urine, so it could be the meds, or it could be something else. Question: Have you posted lab readings and history of Coonsie to the FHL? You may find that they may be able to have better answers for you as to what is going on. Thanks for patience... it is appreciated by me as well. betty and her blur o'fur for the love of ferrets [Posted in FML issue 3783]
