Specifically, does it come in bags bigger than 1.8kg? And if so, where? We're putting Bob and Don (Bob specifically though), on some low cal food, because they're getting a little....... tubby, nothing major, but still. The great thing though is that they looooooooooooove it!!!!! They ignore their regular food we've been mixing the diet with and just eating the diet, so that's great, but with two boys, and eventually my little girl eating the stuff, I need a bigger bag then the dinkie little one I find at petsmart and zellers!!!! ANy idea where I can get bigger bags?
