We decided to take dry food out of my 8 yr. old male's diet (and also the 5 yr. old female, because they have access to each other's food). He was having litter box issues and I thought maybe he was having a hard time digesting the dry food. We also switched his wet food from By Nature to Natural Balance LID Duck and Green Pea. The littler box problems have gone away for almost a week, but both cats are always pestering me for food now that there is no dry food out to graze on through the day. I am usually home during the day so have been giving them a little in the morning, around noon, then again at our dinner time. They eat most of it up in one sitting (a little is usually left that they come back to later), but they are stalking me like they want more food. How much should I be feeding if its all wet food?
