Good morning! Last night I eliminated dry food from Boris's diet. We are trying to feed 300 calories per day, and the volume of wet food required to meet that is a bit more than Boris will eat. Looking for suggestions on what to add to his diet, as he just won't eat more than a can a day of wet food. The other cats end up eating the extra. His current wet foods average approximately 180 calories per can... What high calorie, low carb additions can I make? Thanks!
