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.

Real Turkey is the First Ingredient!

I have been feeding my two cats (both 9 years old) Sensitive Systems for a year now. One of my cats would frequently throw up right after eating, and this has lessened now. I'm happy that both cats enjoy their meals! (This review was collected as part of a promotion.)

My Cat LOVES this food!

I have tried tons of different cat foods along the years because my cat seems to have a very sensitive stomach. With others brands he would get sick after eating ALL the time. Since I have switched to Purina One for adult cats he has not gotten sick once! He loves it and it has been my brand of choice going on 3+ years meow. :) (This review was collected as part of a promotion.)

Best food we have used

My cat has indigestion problems she is a calico and I have heard that they are prone to them. We tried several other reputable brands with no success. Let me put it this way her butt stank with every food we tried! So I turned to purine one sensitive system and no more foul odors from digestive problems! This product gets an a+ for quality while a bit pricy it's worth it for my kitty's belly and the sake of my nose!!

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!

sensitive systems

when I got my kitten a year ago, she was having trouble digesting her kitten food, so I switched to Purina One sensitive systems and she has not had any problems since.
