      Without all of the cut & paste references, I was asking what DRY FOOD
      you feel is better than Innova or California Natural. In a perfect
      world, meat only supplemented with taurine would be great, but that
      wasn't the question. I've read all of the material and research on
      my own, previously, and these brands are the very best in DRY
      food...Don't you think?
