Why do you think I had to get more mice?
Actually, I froze it into 5 containers, I figured I would feed one container a week (like 1/2 a cup). I ended up throwing away 1/2 that first container. (if you look in the dish in the second pic, that's what they have) The new mice haven't encountered real food before (you can't tell me that old dry grain mix at the pet store is actually "food"). So they were quite puzzled when the first mouse pushed past them and dove in the bowl. They'll get the hang of it. They have a grain mix also, but it's not crap, it's a 7 grain hot cereal mix with oats and rice and wheat and flax and a few (three, I presume), other grains that I can't remember.
