Recommended Daily Feeding Amounts: Small (5-9 lbs): 1/3 to 1/2 cup; Large (13-20 lbs): 1 to 1-1/3 cup. Adult Cat Feeding: Fill your cat's bowl with the recommended measured amount every morning and allow your cat to eat on a free choice basis throughout the day, rather than as a single feeding at mealtime. Food intake required to maintain an ideal body condition will vary, depending on age, activity and environment. Monitor your cat's weight and adjust food amount accordingly. It's not for all cats. Purina ONE Vibrant Maturity 7+ Senior formula is specifically formulated for adult cats. Making the switch Purina ONE? Although you'll be anxious to see the difference Purina ONE can make in your cat, please allow seven to ten days to ease the transition from her current food. Each day, simply feed a little less of the previous food and a little more of Purina ONE until you're feeding Purina ONE exclusively. This gradual transition will help avoid dietary upsets. Fresh water, proper diet & veterinary care. Be sure to provide fresh water in a clean container for your cat daily. Proper diet, exercise and veterinary care are the best ways to keep your cat healthy. Store in a cool, dry place.
