Kitty Kuisine Natural Fish Flakes is an all-natural fish treat for cats of all ages. It is made from 100% dried Bonito filets, carved paper thin, and has no additives, preservatives, or by-products. Kitty Kuisine possesses a strong fish-like aroma, which entices all felines. Kitty Kuisine is a good source of taurine (39%). Taurine is used in body growth and tissue repair. All Natural No Additives No Preservatives High Protein Healthy Meal Additive Appetite Stimulant No Refrigeration required The makers of Kitty Kuisine developed technology which extracts the oxygen from our containers and immediately seals them tightly. No other Bonito Flakes on the market today are being packaged using this nitrogen sealed technology. This stay-fresh packaging allows our Bonito Flakes to stay as fresh on the store shelf as they were on the day we packaged them. The flakes will maintain their beautiful pinkish-tan color, they will no longer become dry and brittle, and there will be minimal shrinkage and settling.
