Kitty's Wonderbox Disposable Litter Box
Made from non-toxic, fully biodegradable paper, the Kitty’s Wonderbox Disposable Litter Box “breathes” by allowing air to flow through. This helps to neutralize ammonia gases -- often the source of bad litter box odors. The breathability also aids in keeping both the litter and the box drier. Perfect for travel time or use in cages and carriers, the box is equally suited for everyday use. Just be sure to replace it every 2 to 4 weeks. Depending on size, the boxes are $2 to $8 at Jeffers Pet online.
