Living in a house with five cats means we definitely have to deal with cat box issues. Well, ok, Ellen has to deal with them. Because, you know, making me do it might be, well, bad:

Court documents filed in Clallam County Superior Court tie an alleged arson in an apartment complex to a smelly cat litter box.

Besides, it smells bad enough when it just sits there. I can't imagine what the stench would be like if you set it on fire.
