Eliza, I've never tried this myself, but I imagine, as long as there was other stuff surrounding it, that the cage would be okay. What I would do is wedge it in real tight with the other stuff and maybe even put padding around it (or towels, blankets, etc). Hope that helps! ~Becky and Heather and the magnificent Seven: Abby, Andre, Annie, Arthur, Avery, Bob and Peanut! [Posted in FML issue 4046]
