I have a senior cat, and the litterbox has been a challenge with her age! The clay would start to clump between her toes and she'd drag it absolutely everywhere, peed over the sides, I had to line my old box with plastic bags. And I cleaned it often, but it came to be such a chore so frequently. My sister bought this for me after hearing my tales of what I called, "The litterbox Chronicles" and what a relief it has been! I was nervous at first, not sure if she'd use it, but she surprisingly took to it well. Only thing, she does still track he crystals over a decent radius, and my sister even got me the mat (my cat likes to step over the side and not on the mat though XD) but I don't mind sweeping some more since I don't have to spend so much time tending to the box anymore. Very happy with this gift
