has anyone figured out a solution to this problem. I have just been putting a small handful of food in two or three times a day, to avoid accidents on the whole lot...but i was wondering if there was a solution to this issue that someone figured out. I may go on a trip soon, and I doubt the hubs or teen will remember to replace thier small amounts....they do good to remember to fill thier water (I'm the animal keeper here...lol)
