DO NOT and I repeat, DO NOT use the Kaytee Soft Sorbent!!! This is a HORRIBLE product and extremely dusty. It is nothing compared to Carefresh at all. Yes it's cheaper, but why risk the health of your animals? It is so dusty that it stuck so badly to my rats that their whole cage floors were just covered in dust bunnies. There have been many complaints about this product and it's supposed to be dis-continued soon due to respiratory issues from the dust.
