I happened to find this food in Target. It is one pound bag, price $5.39. And on that day there was 15% off pet food, so I bought one bag to see if Nathan likes it, and so far he does.
It seems to use quite good ingredient, and I calculated the % of calories. If I did it right, protein 39-40%, fat 50%, carbs 10-11%. Correct me if I am wrong.
The carbs % is a bit over 10%, but I feed Nathan with other low carbs (2-8%) canned food, so the average carbs % of his diet will be under 10%.
The one pound food has 862 calories, so if a cat needs 170-180 calories daily, it will last 5 days. It is about the same price (if not cheaper) of FF Classic pate canned food.
I may buy more especially if Target has a coupon on it.
