Hey Julie and Sienne,
I wrote out this really long reply and it got deleted so heres goes again. Portia's condition is very complicated. She's had chronic pancreatitis for a year and we just havent been able to get a normal fPL. We dont know if she has IBD since the U/S showed no intestinal thickening and her GI panel (cobalamine and folate levels) were normal. But given the chronicity of her pancreatitis, my vet suspects she also has IBD. We've tried different food, IAMS intestinal plus (low residue), Hills vnison and peas and finally switched to Z/d. After switching to z/d, her fPL came down a little (from 45 to 10) and so we thought we finally had it under control but about a month later (this Nov), she became diabetic and around the same time her fPL went back up to 25. So now what??? Since she's on a high carb diet+pred+pancreatits, any one of these could be causing the diabetes. We dint really know if we should change her diet or reduce the pred. Since we thought the diet may have helped her pancreatitis, we decided to taper the pred. Its been about 10 days since we started to reduce her dose and clinically she appears to be doing worse now. Meatloafing a lot, generally lethargic and acting just not right. So we've stopped the pred taper today and are going to keep it at 3.75mg/day (lowered from 5mg/day). I would ideally love to get her off the z/d. Although we did see a decrease in fPL, it went back up so maybe its not helping a whole lot or enough(?). But right now, with the diabetes stuff+ the decrease in pred dose+ worstening of pain/nausea and god knows what else, I dont want to to throw food change into the mix. Its so complicated with her. Members of the feline pancreatitis support group mentioned this relatively new company called Rayne nutritional diets that make custom Rx diets as well as novel protein/limited ingredient diets that Im interested in trying out at some point. They have a kangroo one with is 60% protein, 15% fat and 7% carb (by dry matter) which would be a huge improvement over z/d but Im not sure how good this company is and when is the right time if at all to make the change. If anyone has any thoughts on the matter, that would be incredibly helpful.
@Sienne, thanks for sending me the article. Ive shown it to my vet in the past. She's actually pretty up to date on pancreatitis which is great!!!
Sorry for the long post but I wanted to be thorough.
