I started my puppies out on that litter. It was kind of expensive in my opinion so I got them to use litter and they didn't eat it...I was afraid they would eat the litter, so far my new puppies from my litter are doing wonderful with just regular cat litter. I kept lots of things they like to chew in the room instead the litter and it seems to work. I have one that raids the litter box out of habit, but I have changed her diet to the best possible food and have started spraying the pan with bitter apple and also have put stuff in her food like Forbid and it is helping curb that horrible habit. She knows I come on glued if I catch her. I realize she tries to keep the den clean, so I clean it immediately the litter box as soon as it is soiled.
