Here's a suggestion for a new litterbox for Nitro (and any other carpet sharks
out there): Rubbermaid vegetable bins.  I have found these to be the perfect
solution to the poop-box problem--they're about 12 X 9 in., 7 in. tall, water-
tight, and easily cleanable.  The price is nice too: they can usually be found
somewhere for about $2.00 (CDN).  They have one partially cut away side, angled
and just the right height to allow access while still keeping the litter in.
They also come in a variety of colors :-).  Give one a try.  (No, I don't work
for the company...)
