I’m not so sure I’m a fan of the sensitive crystal litter. Does it work? Sure. However the white color mixed with cat waste looks terrible after a day or so. I much prefer the blue or lavender crystals as it masks some of the waste that the scooping mechanism misses when in the cleaning cycle. It is very easy to use, and very easy to change the tray. It definitely gets an A+ for making life a little easier. Just not a fan of the white colored crystals.
