I had pet mice and there was a little wild mouse who would sit at the back of my computer desk and watch me, and my pet mice play. after a few weeks of watching, he come up to me when i didn't have my boys out and sat right next to my hand while i had it on the computer mouse and just chilled watching me game like my boys did. i would give him some treats and he would dip but he always came back. mice are super cute and make great pets.
