oh ya, all my mice had at leats 1 wheel, some had 2, I had a ball to put the moms in so they could spend some time away from their babies, they had tubes that ran from one tank to the other (mostly used in the breeding tank), they had random things to chew on, & most liked to be handled & few loved to play with my rat.

all my mice r gone & my rat was put to sleep, due to serious illness & suffering too much
