Well crud, I did not pay attention to whether the ones I bought had bentonite in them. I just grabbed the bag that they had.
I will check that when I get home and I will start soaking them or grinding them up for them. Kind of thought they were a little big to be eating whole.
Thanks for the advice - we are just using them until we get more hay and then we will use them as treats or to add a little bit with their feed.
