Litter pan/box idea for chin that kicks out shavings in the pan

Hi. In the past few days, I noticed that more than half of the shavings that I put in my chin's litter box (pyrex baking dish) were out on the fleece floor every morning when I got up to clean her cage. She must had kicked the shavings out during the night. This makes the cage really messy and hard to clean. I would really appreciate if someone could provide ideas for litter pan/box that would prevent this from happening or any ways to discourage this behavior. Thanks!
