It happens once a month: changing out the litter for clean litter Dumping all the litter into a garbage bag...then scrubbing the inside, sifting shovel, and shovel holder in Lysol disinfectant cleaner and hot water...then drying it off. Then refilling...then spilling some of the litter all over the floor. AAAAAAAAAAAAARRRRRRRRRRRRRRRRGGGGGGGHHHHHHHHHHHHHH!!!! At least I can make an unpleasant job a little bit easier: before filling the box with clean litter spray the bottom of the litter pan with non-stick cooking spray. This will keep most of the clumps from sticking to the bottom of the pan.
