Alexandra, all is not lost: We find those pans are great crunched
up next to bookcases, and shoved upside down under them to prevent
accidently-on-purposes being deposited there.  (As opposed to
accidently-on-porpoises which L. knows about! :-) )  They also work
jammed in next to a stove to prevent a ferret from walking through
there.  Although we haven't used them for litter pots might they work
better if c-clamps held them in place?
