True Instinct Natural Grain Free With Real Ocean Whitefish



Cats are natural carnivores who instinctively crave protein-rich foods in nature, but regular dry food may fall short when it comes to satisfying cats who want a tender, meaty texture at mealtime. This inspired Purina ONE® nutritionists and veterinarians to research what cats get from their diet in nature. Purina ONE True Instinct Natural Grain Free With Real Ocean Whitefish Plus Vitamins & Minerals makes a healthy difference you can see, with natural nutrition that satisfies your cat and helps support lifelong whole body health.

Adult Cat Feeding Instructions

Fill your cat’s bowl with the recommended measured amount every morning and allow her 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®True Instinct Natural Grain Free With Real Ocean Whitefish Plus Vitamins & Minerals is specifically formulated for adult cats. If you have a kitten, or a pregnant or nursing cat, feed Purina ONE Healthy Kitten Formula.

Making the Switch to Purina ONE?

Although you’ll be anxious to see the difference Purina ONE can make in your cat, please allow 7-10 days to ease the transition from your cat’s current food. Each day, simply feed a little less of the previous food and a little more Purina ONE until you’re feeding Purina ONE exclusively. This gradual transition will help avoid dietary upsets.

No Supplements Necessary

Purina ONE provides 100% complete and balanced nutrition for maintenance of adult cats. There is no need to add vitamins, minerals or other supplements, unless specifically directed by a veterinarian.

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. If your cat hasn’t had a check-up in the past year, please make an appointment today.
