Sensitive Systems

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.

I bought this food because my cat, who is over , seemed to be having trouble coping with regular dry food. She was getting skinny and listless, and even after deworming her and treating her for parasites, I saw that she was still getting stomach upset. When I saw, "Sensitive Systems," on the package, I had to try it. My old kitty is once more the terror of the neighborhood, hunting down rodents by the dozen per day, playing with strings and other chase-ables, and looking sleek and shiny. She has shown no sign of stomach or digestive upset since starting this food. Purina ONE for Sensitive Systems truly brought new life to my old kitty.

My cats won't eat anything else

I have a Maine coon and a Ragdoll. Both tend to vomit now and then. Sensitive systems food helps tremendously with that. My Maine coon has a tendency for bladder stones and the one for Urinary tract health has meant fewer trips to the vet for this issue. Very happy with this product!

Amazing results!!

We had recently noticed some bald patches on one of our cats and after a little research we decided to try switching the food we were giving them as we'd read that sometimes the food can cause reactions like that in cats.
After a little more research, we decided to try Purina One Sensitive Systems and it has totally worked to clear up her skin condition. So glad we chose Purina, we won't be feeding any of our pets anything but anymore. (This review was collected as part of a promotion.)

Purina One Sensitive Systems

For several years our cats enjoyed eating Purina Indoor Dry Formula. One of our cats developed an irritable bowel condition due to her advanced age and suffered from diarrhea. She drank lots of water to stay hydrated. We wanted to ease her discomfort, so our vet prescribed medication and recommended Hills Prescription Diet i/d dry and wet, neither of which she enjoyed, and the problem remained. We switched her to Purina One Sensitive Systems after reading the label while shopping. Along with her medicine, she improved dramatically. She enjoys Sensitive Systems and our vet approves the use of the new food. Our girl has become more alert and playful again and we couldn't be happier.

Improved health and coat!

One of my Siamese has had health problems since he was a youngster. His coat has been rough, he has a cough, he has vomited on a regular basis. After testing, countless vet visits, antihistamines, expensive cat food, I switched to Purina One dry food. This is the one I tried for him first and it stopped his vomiting immediately. Gradually his coat improved. His weight dropped. (He needed to lose some) Now his cough is gone. His coat continues to improve- it is like silk. I can't believe it. Now I mix it with the new Immune System Purina One to improve his immune system. After all these vet bills, I am so impressed with this product line. Way to go Purina!! Thank you!!

picky eaters love it.

I changed to this food because the ingredients looks better then the last food they were eating. I had to change to a gentle food because my one cats stomach does not agree with most foods. This brand is agreeing with him just fine. No surprises when he eats and the bowl is always empty each morning. [This review was collected as part of a promotion.]

A healthy cat food

We were sent a sample bag of this and all 3 of our cats went crazy for it. The only stuff we have been able to feed our cats was frisskies. We have tryed many other brands and they just would not eat it but this new product they sent us they loved so much so now we are buying this for them and they seem very happy with it. Its a very healthy food for them which makes my wife and i very happy.Our cats all thank Purina for the awsome food. (This review was collected as part of a promotion.)
