Kitty Litter, a burning question.?

As a long time cat mom, I would say no. I've never heard of anyone burning it in their fireplace, but I'd imagine the smell (whether #1 or 2) would be absolutely foul, especially in your own home!! I would recommend purchasing a product such as the Litter Locker, OR disposing of the kitty waste in a plastic bag then throwing it in your trash can for weekly pickup... it would take very little space in your trash and also better for yourself I'd imagine.
