I would like to use D-Mannose powder to prevent and/or treat UTI in kitties. Is anyone doing this? If so, would appreciate name of brands you have found useful. My concern: the FDA has stated that, at times, some nutritional additives do not contain any or too few of the claimed ingredients. Just a rip off! All suggestions will be appreciated. My newly inherited triplets (about 8 mo. old) do not have FD. Best wishes, Sophie and Pudge (GA)
