mice like a variety of things... but cheese is not one of them LOL (sorry couldn't resist) you can give them cereal (dry), crackers, goldfish crackers are a big hit as well, cooked pasta, cooked rice... dog biscuits, to name just a few of the things they enjoy.

if they are having a hard time figuring out the spout it made to get water from... putting a little tiny bit of peanut butter on the end of the spout will get them licking it off and voila, they are getting water!

i always use water bottles for my mice, bred hundreds of them a few years ago for an owl/birdsofprey rescue center... they do great.

also, you can go to a feed store and get powdered electrolytes and vitamins - adding a small amount to their water assists with keeping them healthy
