Kittens generally nibble solid foods at 3 - 4 weeks of age. Keep moistened Pro Plan available to these kittens at all times. After weaning, at 6 - 8 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 Pro Plan, changing frequently to ensure freshness. As kittens near adulthood, their calorie needs may decrease. Continue to adjust the amount you feed to maintain your kitten in ideal body condition and avoid excess weight gain.
