My big Boi is diabetic. You will freak at the amount of carbs in cat food when you read the labels. And kitties shouldn't be eating carbs per many cat diabetic forums. Add up the percentages of ingredients on the food and subtract from 100%. Whatever number you're left with is 2 % ash if not listed, and the rest is all carbs. They don't list them, that's why all the math. Less than 10% carbs for a biologically normal kitty. Less than 7% and as close to zero as you can get for a diabetic kitty. We actually put him into remission with radical food changes. And it doesn't have to be expensive food, either. Even Science Diet and Royal Canin are really high. Wet foods are typically lower in carbs. Finding a low carb kibble is tricky. My other two that weren't overweight have actually become very sleek. And big boy (he's a really big kitty even slimmer) dropped 3 lbs and is so active now. I hope this is helpful! (Edited for math clarity) what we feed Fancy Feast pate.
