hi all. i'm posting for some information. my friend works at a research lab and tonight surprised me with 3 mice that were set to die on tuesday. please don't bash me for her decision, i had no idea she was planning this. now i have 3 female white mice in a laboratory cage. what do i need to be a good mouse owner? obviously, they'll need a new cage. what is best? what type of bedding? anything else i need to know? thanks so much.
