I don't know if it's advisable but if you can't get a smaller hide, I'm wondering if maybe you could put something in the hide to help take up the space...like newspaper balls or something? It's just an idea!

We thought we lost our girl and after tearing up half of my son's room (and cleaning it) we found her safe and sound under her waterdish. That was only the second time she had done it and also the last time...never really did figure out why she got under it.
