I have seen this kitty litter
on the GFN there are sites which
there is also the Prima guide for GF
and there is a forum for asking for help
it is down at bottom of main forum page
I am sure some one who has played game
might help you out, but even if they
give you the clue actually solve
the puzzle, do not by pass it because
sometimes not getting one puzzle
leads to insight when you get stuck
later on, plus if you by pass you
miss snappy patter or funny sceens.
take a day or two relax and try again
Manny will overcome.
