Review on Review: Arm & Hammer Ultra Last Clumping Cat Litter 40lb – Superior Clumping Power and Long-lasting Odor Control by Brooke Washington

We like this fountain pen very much. It's great at removing odors and has pretty good absorbency. There's still a little coating on the bottom of the pan, but that's okay. The biggest problem is what is somehow inevitable. The dust covering the room the tray is in seems a little heavier than usual. As long as you keep it in a space where you don't mind a little dust, it's a pretty good thing. If a bit of dust bothers you, you might want to look at something else.
