Feeding Instructions. Kittens generally nibble solid foods at three to four weeks of age. Keep moistened Meow Mix® Kitten L'il Nibbles® cat food available to these kittens at all times. After weaning at six to eight weeks of age kittens will normally eat dry or moistened food at will. If water is added use no more than one part warm (not hot) liquid to three parts Meow Mix® Kitten L'il Nibbles® cat food changing frequently to ensure freshness.
