I feel really awful but ive taken my sisters 2 mice out of her room for the night, she takes their wheel out at night because she's 10 and she can't sleep with the noise, mum doesn't want them and we can't keep them downstairs because of the dog! I put their wheel in and one ran none stop for an hour, shows how exercise deprived they are. She's only young and doesn't get them being nocturnal and such, but I don't want to put them back to leave them pretty much neglected of exercise. What do I do?!
