Omega-3 and omega-6 essential fatty acids are especially good for the health of your cat's skin and coat. Symptoms that suggest your cat needs to adjust their diet could be caused by an inadequate intake of specific amino acids. The unique nutrient complex found in ROYAL CANIN® Hair & Skin Care supports the function of the skin's barrier. It has premium proteins, such as particular amino acids, to support healthy skin renewal and hair growth. A crucial blend of omega-3 and omega-6 fatty acids is also present in ROYAL CANIN® Hair & Skin Care because of their positive effects on coat condition and skin health. Along with fish oil, this formula also includes soy and borage oil, which are high in gamma linolenic acids.
