Hi There,

I'd like to way in as a cat owner on the litter comment...as far as i'm concerned the less harmful it is if she eats it the better (cats dig around, lick their paws, etc.).  (So yes, probably plant based is better than clay).  That said, the problem I usually have with the plant based litters is they are very light.  Which means when she digs it ends up EVERYWHERE.

Hope this helps!
