Royal Canin Kitten food was created to meet the specific requirements of growing kittens. The digestive system, immune system and bone structure continue to develop throughout the first year and this dry food formula contains a combination of highly digestible proteins (L.I.P.), specific fibres, vitamins and minerals to support the growth of all these systems. Immune system support : Growth is an essential stage in the kitten’s life: it is the time of big changes, discoveries and new encounters. During this key period, the kitten’s immune system develops gradually. Kitten helps support the 2nd age kitten’s natural defences thanks particularly to a patented* complex of antioxidants including vitamin E.
