I found a wee little mousie....?

it is a basic field mouse--only about an inch long--it fell out of my ceiling light in my kitchen--hit the chair below it about 5 mins after one of my cats vacated it. he was dazed and sluggish-so i put him in a fishbowl i have with tp and a chunk of bread, and an apple slice--he slept most of the day and ate--now he is all perky and bouncy and whatnot--what can i do to make him comfy until i can get a real tank and i guess a teeny tiny water bottle? tx for any info....
