I like this product, it works well for me. I use it when I am gone 2-3 days. I freeze about half the cat's food (in the tray)and refrigerate the rest before putting it in. I also use the ice trays. This way I avoid the problem some people have had with the food going bad. The frozen portion thaws out slowly. When you prepare the tray, be sure the food is in the right slot and rotation so that the frozen food is accessed last.
