Has anyone tried Evanger's canned food? It is pricey, $1.75 for a 6 oz can, but it says 100% buffalo (or pheasant or duck), and the label said buffalo, water. No preservatives or sugars or anything, which seems pretty cool to me. We won't feed it often, but I think we might use it as a treat. Does anyone know if this is good stuff? Scarlett loved it.
