They've changed the recipe, or at least it seems that way. Before, they loved it and it smelled amazing. Now they still eat it, but they're not as enthusiastic, and the smell has changed—it smells smoky, not like it used to.
Such a shame, but this was a really bad purchase. The cat doesn't even like the smell. I've even tried to trick it by mixing it with plain chicken fillet, but no – just had to throw it away. I'm not going to waste any more time or money on this.
