Feeding Guidelines

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® Hairball Formula is specifically formulated for adult cats. If you have a kitten, or a pregnant or nursing cat, feed Purina ONE SMARTBLEND 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 the 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.

Great food

My Miss Kitty loved the food as soon as I put it in her bowl. Thank you Purina One. I adopted her from the shelter a little over a month ago and making sure she gets the right nutrition. She is about 1 year ago. [This review was collected as part of a promotion.]

My cats love it!

My cats love it and are no longer vomiting as soon as they eat their food. This is the only kind of cat food I've found that my Taffy (who has a sensitive stomach) can eat! Thanks Purina! (This review was collected as part of a promotion.)

Happy Cats

My 4 fur babies really love this food. I have two long hair kitties that had trouble with hair balls. Since eating this food, things have been much better. They seem to love the taste.

Soft coat, cats love the food

My 3 cats eat only Purina One dry foods. They love the foods, never turn their noses up at it, and they have noticeably softer coats with this food. Times in the past when I've purchased other dry foods and then went back to Purina One, I could tell within 1 day the difference in their coats. They get a rotation of Salmon & Tuna, Hairball, and Chicken Tenders.

Great buy for $$$$

Having 2 Persian cats, I have had great success with this product. Over a period of 5 years minimal hairballs from 2 cats. I have tried other products which cause stomach/bowel issues, etc. I would definitely recommend Purina One

Greatest dry food

My 9 cats love this food. Less hairballs and easy to digest for my cat with sensitive stomach. I will not use any other dry food.
