From the Weruva website:
Our formulas are produced in a human food facility using many of the ingredients and processes that are used in products made for people. Our base proteins of chicken, beef and fish include only top quality muscle meat, such as white breast chicken, whole tuna loins and select cuts of beef. Then we add fresh vegetables and other unique items such as Grilld skipjack, tilapia and red bigeye tuna, as well as calamari and shirasu. Our ingredients maintain a natural look and recognizable texture which allows the pet owner to see and understand the ingredients…so what you see is what you get!
