Welcome to the list Linda!
 
You will probabley get a lot of suggestions for your ferrets' litter box
problems.  Here's mine... What we did was we got one of the the high backed
rectangular litter pans AND a small low sided cat litter box.  We wire the
cat litter box (no litter, empty) to the cage and then we put the high
backed rectangular litter pan (filled with litter) inside the cat litter
box.  That way the actual litter box that has to be emptied is not wired
in (we tried that, it gets to be a pain attaching and unattaching for
cleaning).  The cat litter pan holds the other litter pan and keeps it from
getting tumped over.
 
Maybe this suggestion will help.  Good Luck!
