It was funny! Thankfully, throughout all the time I have been working with cats, I have never had litterbox issues with them unless they are ill and are *trying* to get my attention. I change litter brands frequently on them and none have complained......yet....
My cats use "Play Sand" these days....As a matter of fact, we dug two outdoor litter boxes in their outdoor cat enclosure. It's kind of like living on a farm over here lately.......
Prior to building the outdoor enclosure, we used Publix brand because no matter what, all four litter boxes had to be scooped daily and changed weekly....so we didn't see the need to spend extra money...the litter didn't stick around that long.
