OK, so in keeping with our strange pets with strange habits (Nancy has an un-natural fear of paper, Boo is afraid of starving, Angel eats cat poop, Pepper the rabbit is an attack rabbit and Dozer is... well... Dozer).
Sato HAS to be the first to test out a freshly cleaned litter box. As soon as I begin cleaning it he runs from wherever he is in the house to observe my cleaning skills. he then climbs into the box and "Drops a Zag" while I am trying to work.
Very discouraging (not to mention disgusting).
