When I looked at the can of Merrick BG chicken today, I noticed that the label says "feed an adult cat one can (5.5oz) per 6 lbs body weight daily." Does this mean that 12 lbs cat should or it is okay to eat 2 cans? I was wodnering if linear math equation works like this on this matter. I appreciate if somebody with brain can help me with this dumb question. Thank you!
