I had been looking at self cleaning litter boxes for a little while, because I had decided that would be my (and my cats) treat with my tax refund earlier this year. A lot of other boxes required regular litter and were a lot more expensive, so I decided on these. I originally only bought one, because I wanted to make sure my cats would use the crystals as opposed to the litter that they were used to. 

They love these boxes, because I wasn’t always the best at keeping up on their boxes before, and I love them too, because less cleaning for me, and they really do absorb all of the odor. 

Anytime anyone has wondered about good litter and self cleaning boxes, I’ve jumped right in and recommended these. Absolutely worth the extra money.
