My mice are very happy eating this food, it is one of the best and I will keep them on this one. Although it is expensive for a small bag it is very healthy and does not have all treated or messy ingredients included making it more beneficial for the mouse. It comes in fairly large cream biscuit like pellets which do not make a mess and the mouse can easily lift them and bite pieces from them. You do not need to feed them a lot of these as they are large and filling. I recommend these for use on mice and other pets! you can also buy this brand just about anywhere!
