My cat Lucy was diagnosed with diabetes last year and I switched her food to a low carb diet using Fancy Feast Classics. She has been insulin free for a year and counting. Her sister Ethel has now been diagnosed with IBD. We have to change their diet so that Ethel can eat a more digestible diet (they eat together and not separate). I found Nature's Variety Instinct line and read that it was low in carbs - good for a diabetic cat as well as one with IBD. Has anyone tried this food for their diabetic or IBD cat?
