What they call "horse pellets" at farm/feed stores are just wood stove pellets which yes - many of use. I use them for both my cats and ferrets and would never think of using anything else. The problem, though, with what they usually call "horse pellets" is that they are usually bits and pieces of wood stove pellets. I bought these once and they didn't last nearly as long as the regular wood stove pellets since the pieces are broken up. They're basically the "reject" wood stove pellets They're really not much cheaper than the regular wood stove pellets and since they don't last very long, not worth the lower price. Go with the intact wood stove pellets. Of course a store by you may call regular wood stove pellets "horse pellets" so just look at them before buying them. Hopefully they're in a clear bag so you can see if they're full pellets or pieces and sawdust. Laura [Posted in FML 7403]
