I'm glad to hear that your kitties like the Wysong. I haven't tried that one yet. Mine have gotten so picky, it makes me nuts. I gave a friend of mine a bag of Wellness dry, because they woudn't touch, it. they also didn't like Solid Gold,Innova, or EaglePack.
right now, I had been giving them Royal Canin for awhile, but they seem to be getting bored with that too. I may try the Wysong, or Evolve.
