Your kitten's growth may slow down around four months of age, but their activity levels are increasing! Your kitten needs the correct nutrients during this stage to support the development of its bones, muscles, organs, immune system, and nervous system. Your kitten will grow 30 adult teeth very soon as well. A unique formula known as ROYAL CANIN® Kitten in Jelly is designed to meet the nutritional requirements of kittens during the "consolidation phase"§ of their development. Kittens between the ages of 4 and 12 months should use this formula since they are going through a period of significant behavioral and physical changes. This customized food provides moist jelly chunks that are just the right size, texture, and flavor for developing kittens. Vitamins C and E are among the nutrients it also contains.
