I talked to one of the vets yesterday about my aunt's cat. He has lost over a lb since last April and his coat is crappy (oily, dandruffy, mats), has soft stool/diarrhea and he is ravenous all the time. His Free T4 by ED came back totally normal (39 in a 20-50 normal range) and his BG was 219 (non-fasting, vet stress - when I test him at home he is in the 7-80s). So the vet suggested using digestive enzymes like Prozyme in his food.
I had never heard of Prozyme, so I don't know if it is good, bad, or useless. It has lactose in it, which I would think would be bad for cats. There is a "plus" formula that does not have lactose. I'm going to post on Health and see is anyone here has used it, but I wonder if Mickey needs something like that? Or FortiFlora. The vet said that might help too, but he seemed to favor Prozyme. But when vets Rx dry foods from Hills, I have to wonder about how much they really know about something like Prozyme or if the company rep just gave a good shpeel about it - and a commission.
