Wouldn’t Wysong qualify? It has its own plant and was one of the first companies to actually care about ingredients. Its innovations are really quite extraordinary. It has always been most willing to share its procedures and methods, but may not be as forthcoming lately due to Purina (or Iams, can’t remember) taking info from Wysong (regarding the adding of probiotics) patenting it themselves, and then suing Wysong for using its own recipes. So much for being willing to share for the greater good!
