Think about it. I would still tend to worry about the fact that most ferrets will wipe their butts in the litter after they use the litterbox. The clumping litter will stick to them if they do that, which can cause lots of irritation. If they try to lick it off, there is also a danger that they will swallow it and possibly develop an obstruction. Sounds like the "regular litter" used may have been clay litter, which does not work very well with ferrets due to all the dust. I personally prefer to use something I know will be safe for my babies, such as the woodstove pellets or newspaper pellets. One of my babies will play bulldozer through the woodstove pellets if the litter box is very clean, but it does not seem to hurt him in any way. If they were to swallow the wood pellets or the newspaper pellets, odds are it wouldn't really hurt them in long run. I don't mean to be judgemental toward anyone who uses clumping litter, and it may work out fine for some ferrets, but there are potential problems with it. Why not play it safe?
