Hello! I would like to purchase some dry cat food to give my diabetic kitty a few kibbles as a treat once in a while, and to feed my non-diabetic kitty along with his wet food. I am looking at Wellness Core and Instinct Raw Boost. Does anyone know which of these would be better to use or have any opinions on these foods? I don't really know what to look for besides high protein low carb, and I'm not able to find the carb % online for these two. Thanks!
