We have two cats, Reagan and Madison. Reagan was just diagnosed with diabetes. Madison has had pancreatitis before but with treatment she is better now. Just switched them to all can food, but wondering how much to feed? Going to feed twice a day. Read some articles that say 4 to 6oz a day but thecan of Fancy Feast says 1 can per 2 1/2lb. That would be like 15oz of food for Reegan and 12oz for Madison a day and I think that’s way too much!!! Any advice is appreciated.
