Product Overview

Purina ONE® Sensitive Systems starts with your adult cat’s nutritional needs first to help support her optimal health, inside and out. With real turkey as the number one ingredient – and 0% fillers – all of our high-quality ingredients have a purpose. Omega-6 fatty acids, including linoleic acid, plus Vitamins E and A, help avoid dry, flaky skin and promote a vibrant coat and bright eyes. This formula also promotes easy digestion. With 36g of protein per cup, it provides the protein your cat needs as a carnivore and helps support strong muscles, including a healthy heart. It is enriched with vitamins and minerals for strong bones and joints, and the crunchy kibble helps reduce plaque build-up and whiten teeth. And, because it is highly digestible, more nutrition goes to work inside your cat. Plus, it has a taste cats love. Purina ONE provides purposeful nutrition for lifelong whole body health. Purina ONE nutrition is veterinarian recommended and proudly manufactured at Purina-owned U.S. facilities.

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.

Feed Only ONE

A cat's digestive system works best when it receives the same food each day. Although humans crave variety in their diets, cats do not. Feeding different cat foods can turn your cat into a finicky eater. Avoid feeding table scraps, as they can upset the nutrient balance provided by your cat's regular food, and may lead to obesity. For questions related to the health of your cat, see your veterinarian.

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.

Older cat

1 of my 5 cats are 12 years old and started having trouble digesting her food. She would throw up all day. Switched to purinaone and she feels so much better. Highly recommend for older cats.

Our "rescue" Charlie just does wonderful on this food!!

We rescued our "Charlie Cat" and she has been with us for 6 years now. Since moving to a dry climate in Arizona, she developed a dry coat and started loosing more hair. She always tried to clean herself, but then developed hair ball problems. She is on her second bag (8 pounds) of this food and definitely helped the problem. We want to keep her as long as we can and feel this healthy diet will enhance her ability to live a long healthy life. BTW: The coupons did not print, but we plan to continue buying this food.

Quality food takes care of our cat's needs

Not only have I switched my cats to this food with excellent results (2 of the 3 were having stomach problems and couldn't keep other foods down), but I volunteer at a small humane society and we also use it with excellent results. So many animals today are having trouble digesting foods made with dyes and who knows what else, but after we switch them to Purina One products, they do remarkably well. We recommend it to our adopters and friends alike.

my cat loves it!

I received a sample of this project from influenster. After giving some to my cat, I could tell she loved it. I ended up buying the bag for sensitive systems as she is older and was having trouble with going to the bathroom. I saw a change for the better in just a few days. I will definitely be making the switch permanent.

Thank You ! Kitty is having good Bowel Movements !

Thank you ever so much for this food . My Miss Kitty in 15 years old . She was having problems with her bowel movements . Even to the point of me having to take her several times a year to be cleaned out at the Vet . Her stool was large dry, and very hard . After having her on the vet suggested food for hair balls which did no good I found the Sensitive Systems formula .
Within two weeks she was having regular movements every day . After another week her movements were moist and smaller and easier for her to pass .
Thanks to this food she is feeling better and not hiding in the closet anymore.

Thank you .

My new cat just loves this!!!

I just adopted my cat from a shelter and she is so sweet! She just loves this formula, she comes out whenever I fill her bowl. I guess she is used to this particular formula because I am following what the shelter suggested. And it is all natural with Chicken being the first ingredient. No wheat gluten. I am happy with this product.

Good Food for Cats

We have been using the Purina One Smartblend Sensitive Systems Formula for a number of years. We are very happy with this brand for our 4 cats and they love it. It has helped a lot with our cats not upchucking after eating. We are very happy with this brand and will continue to use with our cats and any future cats we own.

Easy transition

My senior cat developed GI problems. He was vomiting and had diarrhea. My vet suggested a food change. I decided to try purina one. My cat loved it, making an easy transition from his old food. He hasn't vomited since he started your food and his diarrhea is getting better by the day. So glad I chose this brand.

Worked for my sensitive stomach cats

After trying 5 different foods (prescription & non-prescription), I finally discovered Purina One Sensitive Systems. I have 4 cats, all love the taste and the two with
sensitive stomachs are doing great with no more symptoms.
This is an excellent food.
