I don't think it's a matter of how many carbs a day, or meal like with human diabetics (or anyone watching carb intake). I think it's the carb percentage of the food we feed that is calculated, the wet food with 10% or less carb content. And of course the other components, protein, fat and phosphorus is important. I use food that is lower than 7% carb, and I make sure that Idjit gets around 300 calories a day. He had lost weight at diagnosis, gained a little back, now he is in really good shape, lean and sleek. He was getting too tubby before the diabetic weight loss started. I make sure he has extra protein with the baked chicken and fish.
At first, until I could remember what the carb and calorie count was for each variety, I took a marker and marked the carb and calorie count for each can on the label. Then I could calculate how much to feed a day, so he got enough calories. When we used up all the medium carb food that we had and there were no more cans with more than 7%, I didn't have do that any longer. I know the Fancy Feast cans (3 oz) are a bit less than 100 calories, and the Fancy Feast cans (5.5 oz) are a bit less than 200 calories. I still have my handwritten table of the varieties we buy, and can refer to when needed. When I buy the larger cans of Friskies, I measure 1/3 cup per serving, which would be 1/2 of a 5.5 oz can.
My next venture will be higher protein wet food, like Weruva and Tiki Cat. I have been trying to find it in stock in town, without success so far. I am hoping to find some so I can buy one can of each variety/flavor to see if he likes it. I don't want to order cases from Chewy and have him not eat it.
