Rated 4 out of 5 by A happier Furbaby means a happier momma! I've been racking my brain since my baby cat Kiara got older and seemed to have a very upset stomach when eating. I've always had her as an indoor kitty and so i fed her the indoor formula cat chow. she loved it! But as she got older her stomach needs became a problem. She would often throw up what she had eaten frequently and sometimes several times a day. the store that was in the small town where we resided kept a small supply and variety of cat foods. We moved to a larger city and I discovered sensitive systems. It's worked wonders for her. she is throwing up less and less as time goes on. she's a happier furbaby and I'm a happier momma because of it! January 14, 2015
Rated 5 out of 5 by Our Cat Thrives We switched to Purina ONE Sensitive because of vomiting issues we experience with another premium science based diet. Our indoor cat eats this better and the vomiting issues went away after we switched. Litter box cleaning is easier as well. This formula is more available and costs less then the previous brand which was recommended by our veterinarian. Over my 50 years, our cats have always preferred Purina cat chows over other brands and this formula is not different. The neighbor cat also enjoys it and visits often for his special treat. I have used Purina chows for all of our farm animals and none have let me down. Quality is built into the product regardless of species. November 21, 2014
Rated 5 out of 5 by Finally my cat gained weight! My shorthair orange tabby was thin his whole life, and finally at 8 years old we switched to Purina One Sensitive Systems and he has stopped throwing up and his stomach is not sunk in any more!!! He has never looked this healthy and his fur is way softer too!!! I love this cat food, thank you Purina One!!! XXXOOO October 22, 2014
Rated 5 out of 5 by 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. June 13, 2014
Rated 5 out of 5 by Small bites and great for cat with allergies Ive only used Purina products my entire life its what my parent and grandparent have always used with thier pets. I have a cat with mutliple allergies and this food has been great in findin something he can eat that wont cause a allergic reaction. I hope it continues to help us. Ive tried mutliple products gettin the same results allergies so far all my cats and I own 5 ages very all are adult cats. Ranges from domestic short medium and one long hair its doin a great job with coats and digestive systems like I said it has small pieces which are great for my two year old he has a hard time pickin his food from the allergies but this one has none of that.

Rated 5 out of 5 by It works Raphie was having trouble with diarrhea and throwing up. Vet recommended I try a cat food for sensitive stomachs. I tried this product and stuck with it. Problems have resolved and Raphie loves it. June 13, 2014
Rated 4 out of 5 by All my kitties have sensitive tummies All three of my kitties ate Purina's Sensitive Systems for several years and seemed to enjoy it - particularly the small pieces (which all Purina One dry formulas have now#. For years, all dry cat foods had huge, dog-sized pieces that our feline babies had to knaw on with their very small teeth; to combat this, I had to mix the dry w/their wet foods to make the pieces easier to chew, swallow and digest quicker. This formula seemed to be less harsh on their digestive systems and we had fewer and fewer "throw-up" episodes over time.I am still using Sensitive Systems, mixing 1:1 with Purina NF dry renal food - since they became 15 this year and require kidney health monitoring - mixing the 2 products makes the dry food more attractive to their palates and gives them a familiar taste instead of an entire change from one they love to the not-so-tasty kidney product #which by necessity is blander).Purina has been the mainstay of all of my many kitties' lives for over 40 years, so you can count on its quality and healthy outcome for your felines!!

Rated 5 out of 5 by Went from expensive premium dry cat food to this, with GREAT results! My indoor-only short-haired cat just turned 3 and started throwing up his food each time he ate, immediately after eating. I took him to the vet, who ran tests and found nothing wrong. The vet prescribed a VERY expensive food that the cat tried to cover up (yep, it was THAT bad!!). I tumbled to the fact that my cat might be sensitive to chicken, his main previous diet and preferred protein source. So, I tried four other sensitive stomach non-prescription brands (many had chicken ingredients buried in them), stopping with this one. He loves this food and has only thrown up once since on it, producing two large hairballs...and very little food, at that. What a change! The very positive results: no more nighttime kitty vomiting (which woke me up) and a much happier cat who eagerly chomps away on his Purina One dry cat food for sensitive stomach. Since the turkey agrees with him, I have also been supplementing with Purina One turkey (with gravy) wet cat food. My budget loves this Purina One, too! [It helps me afford the expensive Maine Coon food for my 20-pound Maine Coon! ;-) ] April 26, 2014
Rated 4 out of 5 by They love it We have 2 fairly pick eaters, and one has a tendency to eat to fast. Needless to say, we are constantly cleaning up after her. They seem to love the sensitive system formula. is a little to early to tell if it is working yet, as we just started giving it to them. Just a little more on the expensive side, so we are not sure if we are going to be able to continue to get it for them. may have to mix it with the other food to make it last longer, or only get a bag once in a while.

Rated 5 out of 5 by Excellent food I tried it because both of my cats had issues. I have noticed less vomiting. My female has food allergies and she has been eating it with no problems. My male cat is doing well on it as well. Good stuff June 29, 2015
Rated 4 out of 5 by Good Product My Cats very much liked trying out their new cat food. They seemed to really enjoy the smaller bites and they would run to their bowl when it was feeding time to they really liked the taste. The only thing that concerns me is the fast that it contains corn, soy and wheat which is not good for cats for their digestive system. This product/brand wouldn't be my #1 choice but it's a good alternative.Please note that I received a free product sample in exchange for an honest review. #ONEswitch May 19, 2015
Rated 5 out of 5 by No more spit-ups What a relief. Our cats are 17+ years old and are getting quite frail. Since feeding them the new 'sensitive' Purina dry food, the spit-ups have virtually ceased. Their weight and appearance has improved and they are much happier, more active and healthier. June 23, 2015
Rated 4 out of 5 by Good for indoor or outdoor! I was pleasantly surprised by this cat food. I have a really sensitive nose, and most cat foods stink a lot to me. This one does not. The ingredients are good, so I don't worry about feeding it to my kitty. She can be pretty picky, but dove right into this food with no hesitation!I received this product free to test and review, but all opinions are my own. June 20, 2015
Rated 5 out of 5 by Premium quality and delivers what it says Just gonna keep this simple, my 2 Siamese cats have been eating purina one products for years and have last couple years been using the indoor formula but my cats have started throwing up on occasion. I did some reading on the sensitive formula and decided to try it, wow my cats have not once thrown up one time since they have been eating it and better yet the stool in litter box has really been minimized too. I will be using this formula from now on June 17, 2015
Rated 5 out of 5 by Great food for cats with sensitive systems! Last August we adopted two twin brother cats. I bought the cheaper brand of cat food that I had always gave to my previous kitties and it gave my new boys bad gas and an extremely stinky litter box! I wondered if it was the food I was feeding them, so I needed to make a switch. I then took the Purina One Challenge and tried the sensitive systems blend and I'm so glad I did! It really helped their bellies! After about a week I noticed a decrease in the amount of gas they had and the litter box didn't smell as bad. I don't mind paying a little more so my cats can be comfortable! They also loved the taste a lot more then the cheaper brand! I will continue feeding them Purina One Sensitive Systems! Only the best for my boys! April 15, 2015
Rated 5 out of 5 by My cats love this food! I read the label of the former dry food I bought for my cats, it was not healthy. My four cats were vomiting several times a week. I compared ingredients and price and decided to switch to Purina One Smartblend Sensitive Systems. I followed the directions regarding switching the food gradually. My cats love it. The vomiting has stopped. I told my sister about this great product. My sister switched. Her two cats love it also. My cats ages are one, ten and fourteen. I wish I switched years ago. This dry food is worth every penny. My cats seem healthier and happier. Thank you Purina! June 15, 2014
Rated 5 out of 5 by 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. June 14, 2015
Rated 5 out of 5 by Great for Cats with Sensitive Digestive Systems I have four cats, and two of them have had problems with digestion at times, sometimes having loose bowels or regurgitating. Also, a couple have been overweight. Once I started feeding Purina One Sensitive Systems to them, all of the digestive issues cleared up, and quickly. Also, one cat lost all of the weight she needed to be within a healthy range. This product is also delicious, as they seem to really enjoy eating it. I am very happy with this food. It is not very expensive either, much less than some of the other brands that offer products for digestive issues. I will continue to buy this cat food. June 13, 2014
Rated 5 out of 5 by superior food I have been using sensative ever since some of my older cats have problems with their stomachs. I also use this same food for when I take in foster cats that have had poor diets it is much gentler on the stomach works well and it is good quality also. June 14, 2015
Rated 5 out of 5 by Amazed, My Cats Love This Food! Our 2 ten year old cats began vomiting a week ago every time they ate their dry food that they have been eating for 9 years. We made one vet visit. Vet couldn't see any reason for their vomiting. After not being able to get through one day without one of them vomiting, my husband went out late last night and bought the Purina One for sensitive stomachs. These two cats don't eat anything but their dry food. They don't like any thing else so I never thought they would eat the Purina One. To our amazement, they are both eating the Purina One today! Thank you for this great cat food for sensitive stomachs. September 14, 2014
Rated 5 out of 5 by The only thing that worked My kitty had problems eating and keeping food down for years. We tried everything from wet food, dry food, limited ingredient, and organic all with similar results. We saw a commercial for the sensitive system food and thought it sounded like what she needed. We gave it a try assuming the results would be similar to all the others but it worked. She ate it up and kept it down. It's been a couple months now and she has put on some weight which she needed. I can't thank you enough for this product. I don't know where we would be without it. June 3, 2015
Rated 5 out of 5 by Really helped my 15 year old cat I started feeding Purina sensitive systems to my 15 year old cat Peaches about a year ago. She started to experience problems keeping her food down. It seemed everything we tried irritated her stomach. We picked up a bag of Sensitive systems and immediately noticed her problem went away. Now it is very rare for her to have any stomach problems, which make her happy, and us very happy. June 5, 2014
Rated 5 out of 5 by Thank you This food saved my older cat's life. She's become allergic and we have not been able to identify the allergen. She was vomiting everything . This food stayed with her, she gained weight and is herself again. Thank you so much. September 27, 2014
Rated 5 out of 5 by Helps with Upset Stomach The Sensitive Systems cat food has changed our life. Our 14 year old cat was throwing up on a daily basis. We hadn't changed our cat food in 5+ years, so we didn't think it was the food, just our cat was getting older. But we tried Sensitive Systems, and now it is less than once a month (on the clean-up). And her coat is much nicer too! Thank you Purina One! June 9, 2015
Rated 5 out of 5 by So much better We have two big orange cats and our one boy was suffering from frequent vomiting. We had him checked by our vet to see if something was wrong, but everything came back clean, so we switched to Purina One Sensitive Systems. Things have been so much better. He does not vomit anymore and, an added bonus, his gifts in the litter box are much easier to clean up.We thank you, our carpets thank you, and if he could, Orion would thank you for making an affordable food that he can keep down.

Rated 5 out of 5 by she loves it Vomiting stopped, made for a much happier cat. Food even smells good. A little pricey but worth the health of my cat. May 6, 2015
Rated 5 out of 5 by Lots Less Vomiting My 10-year-old kitty cat, Chloe, has a very sensitive stomach. She was vomiting up her food all the time until I switched her to the Sensitive Systems Lamb and Rice formula. Lamb seems to be the only protein ingredient that her system can tolerate, and Purina One is one of the very few that uses it. I'm very thankful that this food exists for my fussy girl! June 4, 2015
Rated 5 out of 5 by Best Cat food on the market for Sensitive Systems My cat has food allergies which causes him to have bouts of eczema. I tried Purina One for sensitive systems and have not had any further issues with his allergies.My only wish is that it came in a larger bag. June 7, 2015
Rated 5 out of 5 by Sensitive stomach help One of our kitties has a very sensitive stomach, causing diarhhea. We have tries more expensive brands before trying Purina One. I have to be honest, I wanted a name brand that was more affordable as we have 3 dogs and 3 cats and that can be expensive with food and vet bills, etc. Wet ried Purina One for the dogs and they seem to be thriving on it (puppy and adult), so we decided to try the Sensitive Stomach cat food. It has helped - she sometimes still had loose stools, but it has improved. She likes it and she seems to be doing well on it, so we will continue to buy Purina One. May 25, 2015
Rated 5 out of 5 by No more sick bellies We received our first bag of Purina Sensitive Systems dry cat food free as a promotion from #influenster. Naturally, we tried the #OneSwitch but honestly I was not thinking it would make much of a difference. How wrong I was! We have since continued to purchase this brand and will continue to do so! We have an older cat, who despite a clean bill of health, was vommiting daily. A few days into the Purina Sensitive Systems we noticed he was no longer throwing up! So glad we tried the #OneSwitch!!!! May 29, 2015

    Feeding Instructions

    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.
