Royal Canin Kitten is a dry food formulated for cats aged 4 to 12 months, addressing the nutritional requirements of the growth phase. During this period, a kitten's immune system is still developing and energy demands are considerably higher than in adulthood. The 400g size suits households looking to trial the food before committing to a larger bag.

The formula includes a blend of antioxidants — including vitamins C and E — to support the gradual maturation of immune defences during the first year. Protein and fat levels are calibrated for growth rather than maintenance, and the kibble is shaped and sized for a young cat's smaller jaw. Digestive support comes through highly digestible proteins and a balanced fibre blend, helping kittens adapt to dry food without stomach upset.

Royal Canin's life-stage approach is what draws most owners to the range. The kitten formula targets immune immaturity directly rather than simply offering elevated protein — a distinction that matters most in that first year when developmental foundations are established.
