These little ones were wild mice, and man could they jump. Kept them in very deep plastic bins in the bathtub, I finally had to keep the lids on the bins, (they did have air holes) They escapees were pretty tough to catch.

They were so cute. One of them, the largest would sit up in my palm and drink from the eye dropper. I used kitten milk replacer of all things, then eventually weaned them to seeds etc.
