My two are on Breeder Celect (paper), which they used previously. It doesn't smell when wet, so that's good. Some sticks to their paws but I'm not worried about that. As they're eating a lot and consequently weeing a lot, I'm getting through one bag at week, which is £13.99 at PAH.
What does everyone else use?
Someone mentioned kittens may eat litter, so clumping isn't good in their tummies, also they might like something softer under their paws and just wondering if this is really the case.
