“I have four elderly cats and my day job includes testing and reviewing cat products. The clay litter that is an option with Kitty Poo is simply the best clay litter we've ever used. Doesn't track much, emits very little dust, and—absolutely best of all—it dramatically reduces urine scent (while being scentless itself). No idea how they do it, but it's wonderful. We have now switched all our litter boxes, traditional and Kitty Poo cardboard, to Kitty Poo Clay Litter.”
