x-posted from Rabbits Only:
I found these while poking around the web:http://www.petwerks.com/prodpage.cfm?prod_code=MO400
http://www.bunnybytes.com/cgi-bin/start.cgi (click on ‘Supplies’, and on the second page is the SP006m Low Entry Litterpan)
A low-entry grated litterbox would probably be perfect for rabbits that have mobility issues and have difficulty keeping themselves clean.

I’ve made our very own low-entry box for the rabbits’ new home:
Start with one concrete mixing tub from your local home improvement store (Home Depot should know me by name at this point), some kind of non-slip rubbery material (in this case, a pot holder), and Super Glue.
Cut a portion of the rubber to fit on one corner of the box, and glue it in place.

Repeat this for all four corners, and elsewhere if you so desire. You now have a box that won’t slide around the floor.

You may also, as I chose to do, create a grated cover. Illustrations of that procedure are here. As a final modification, I cut down one side to create easier access for older rabbits who may not want to leap in and out of the box. As you can see, Rex loves it.
