I wish I could line the box with newspaper - but if my boys realize there's paper, they dig and dig till they can pull it completely up, and tear it apart. What a mess! I've been using a garbage bag to wrap the entire litter box. Makes cleanup real easy.

My only concern, Baxter n Boo, is that a bunny may decide to chew on the garbage bag and ingest some plastic - which is very bad for them. I have found that if I take a large garbage bag and put the litter pan in it about half way, tip out everything and tap the bottom, nearly all of it dumps in cleanly before I even have to wash or wipe it down. BB's new scooper she's selling in the store works very well for scraping out the final bits, then a rinse, a water/vinegar rinse, and a rinse again gets it super clean.
