i have 2 female mice. they are leftover from feeding my spider and then scenting rats for my her because she only wanted mice when i got her. it was quite successful, and now i have pet mice. and i have to admit, they are kinda cute. i tried to give them away and that fell through so i said what the heck, i'll just keep them. they recently were upgraded to a wire cage with a wheel and other fun goodies. if only i had the energy that those two have--that wheel NEVER STOPS!
