I made my hamster a new bin cage, its basically the same on the bottom, but I added another bin to the top so its now 2 levels. I'm gonna post pics very very soon (within the hour), she really likes it I just need to perfect the ramp, the one now isnt gonna fall but it wobbles shen she goes up it and is scary for her, I'm having my dad make her a really nice one out of wood this weekend.
