“When I ordered, my only concern was if I could flush it. That worked fine if I was home and flushed it quickly. If I was away, the accumulation turned into a hard gel that stuck to the side of the box. It was very messy to clean up. More stuck to their feet to clean up. I hated the extra time it took to clean up. The urine odor was very noticeable. The fine grain silica was much easier to clean up so I’m changing back.”
