Good, but I would get something else as well
This deal was great value, but I think I bored them because after the first box of 40 they went from loving it to much less enthusiastic (and I still had two more boxes to go!). I've been putting a bit of those "liquid snack" things on top to help them eat it. Next time I order in bulk I'll order one box of 12 of something different too to give them variety!
