Rated 5 out of 5 by Quality food my senior cats love! I adopted from the same shelter, 2 senior kitties at different times. Duncan is now 19+, adopted Dec 2014 & Miss Kitty is almost 12, adopted Aug 2015... there are 3 other kitties in my family; Gabby 18, who arrived as a baby in 1998 & Rudy 7, adopted in Sept 2014 and Kevin 3,adopted in June 2015.. had switched all cats to a grain free food recommended by my vet. Unfortunately, Duncan the 19+ year old seemed to have issues digesting the grain free; and Miss Kitty arrived at the shelter needing MAJOR dental with a lot of extractions and it seemed too hard for her to "gum/chew" ... so I switched these two back to Purina One Sensitive Systems. Duncan, the 19+ year old now very rarely vomits up his food and Miss Kitty 12, can "gum/chew" the kibble, because the pieces are smaller & a little more porous ... and they both LOVE the food! And mom is happier that they are having much fewer digestive issues! The other 3 kitties are always at Duncan's & Miss Kitty's dishes... think I will be switching them back too, once the grain-free is gone. Thanks for a great product! May 24, 2016
Rated 4 out of 5 by couldn't print coupons but purina made good by sending me excellent coupons to make up for the problem cats love the food & purina made good on helping me in buying the food, thanks for the support & help in feeding my feline family August 2, 2015
Rated 5 out of 5 by PurinaOne Sensitive Systems Bag... My cat loves this food. It is the only dry food that she will eat. She is VERY picky. If the bowl is 1/2 full she will bite toes to have it filled up.The only problem I have is with the bag...no handle. There is enough room to make a handle. There should be a handle above the seal.

Rated 5 out of 5 by 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!! April 5, 2016
Rated 5 out of 5 by Sensitive Systems food helps my two elderly cats with their sensitive systems Excellent - best brand available for cats with sensitive systems. Highly recommend. May 16, 2016
Rated 5 out of 5 by Only food my cat can keep down I have a 6 year old rescue that has sensitive tummy. He has had issues since he was about 6 months of age. We ran countless tests at the Vet, tried sooo many different foods, many of them prescription diets...spent so much money. He would be fine for a few months and then the barfing would start again. Purina One Sensitive Systems is the ONLY food he has eaten with no vomiting!! He has been on it well over 2 years with great Vet checks, he has finally put some weight on and we have all our adult cats on it! They all look great, their coats are soft & shiny & we love this food! January 20, 2016
Rated 5 out of 5 by All of our kitties love this food We started on this food for another cat we had who had a sensitive stomach, but unfortunately has since passed. We have three kitties on this food right now and they love it. We have no stomach issues with any of them. We mix it with Purina naturals for a little variety :) January 29, 2016
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 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 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 Kitty has a happy tummy now. This formula really lives up to the hype. My 2 yr old medium hair has a very sensitive tummy, Every food we tried he wouldn't digest properly (i.e. vomiting). His vet recommended this and we noticed a difference immediately, plus he loves it. Thanks Purina for creating a great quality product both my boys can enjoy. February 4, 2016
Rated 5 out of 5 by Bye Bye tummy troubles! We started feeding the Sensitive Systems formula to our cat b/c other foods upset his tummy. He loves this food and his tummy issues are gone! I highly recommend this if you are looking for quality at a decent price. Thanks Purina ONE! October 27, 2015
Rated 5 out of 5 by Sensitive Systems I have 4 cats. Thee Ragdolls and 1 Himalayan. I got my last Ragdoll as a rescue about a year ago. He was having severe problems with over grooming and fur pulling. I switched all 4 cats the the Sensitive System brand and it has really helped. He's not 100% better, but noticeably improved. My other cats just love it as their regular food. November 25, 2015
Rated 5 out of 5 by Definitely the choice of all our cats We have 4 female cats at this time, but have had as many as thirteen. They all love it, and have NEVER had a UTI, and this is the only food they all keep down. Previously we used some foods with artificial colors in it (i.e. red, yellow) and they would throw up all the time. We have been feeding the Sensitive systems for as long as it has been on the market. We wouldn't switch if you gave us our cat food for free. September 19, 2015
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 Purrfect! When we brought Brandy home from the shelter, they said she had food allergies and that we should feed her Science Diet (at $26/bag!). When we took her to our vet, (who sells Science Diet) he told us to use the PurineOne Sensitive instead. Brandy loves the taste and she is thriving! August 24, 2015
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 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 5 out of 5 by I've tried others, this is the one I rescued 2 amazing cats from a shelter about 5 years ago. One cat is rather large and fluffy and even though I brushed her daily she kept throwing up. The other cat seemed to exhibit low energy. I tried a few different types of food including a grain free and expensive choices but I was still finding vomit. When I tried Sensitive Systems all of that changed. One cat had better energy and the other quit vomiting. I never buy anything else now. This is the only food I have found that my cats both enjoy and keeps them feeling great. Thank you Purina One. October 11, 2016
Rated 4 out of 5 by Worth the price In the small Iowa grocery store where I purchase Purina One charges an unbelievable price for a small bag. I am unable to travel very far and have no printer to print out coupons. My cats love their food and their coat is shiny and soft. I want the best for them and believe I have found it in Purina One. They are worth the money. October 15, 2016
Rated 5 out of 5 by Love this product Started out when my cat was diagnosed with chicken allergy. Was hard to find a quality food that all my 5 cats would eat. We tried plenty of the expensive and precribed. They all agreed on Sensitive systems he lived 12yrs. Even after he passed away I then tried to change to a non specialty food with chicken. They want sensitive systems. I now have 3 healthy cats ages 15 1/2, 14, and 9. I like the ingredients and quality. Thank you. September 18, 2016
Rated 5 out of 5 by Great food My really likes it. He has not had any trouble since starting the food. September 22, 2016
Rated 5 out of 5 by 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!! September 13, 2016
Rated 5 out of 5 by My cats love it! I have two cats, one of whom has a very sensitive digestive system. She would get sick all the time until we switched. This food has helped tremendously with our poor sensitive girl and our other cat loves it too! September 3, 2016
Rated 5 out of 5 by Great for Calming Stomachs. My oldest cat (of only 2) has a very sensitive stomach. Will eat a small pasture of grass & only ways 4lbs. at best. Ha haBut they not only like the taste; she hads gotten sick in days.No more hairball surprise when getting up!Great product. September 6, 2016
Rated 5 out of 5 by Older Cat - Sensitive stomach My older cat started having trouble with stools & vomiting. I decided to change her brand of food she has eaten for many years to see if that would help. After receiving a sample of the sensitive stomach purina one formula, I found that her problems are solved! She immediately loved the taste of the food and her issues have gotten much better. August 23, 2016
Rated 5 out of 5 by No more upset tummy and pennies in my pocket!!! My 14yr young female cat was diagnosed several years ago with, what the vets thought, irritable bowel. She was vomiting immediately after eating and had bloody diarrhea. She has been on a very expensive hypoallergenic prescription diet which definitely helped her condition. I realized I was running low on her dry food. I decided to check online to see if there was a hypoallergenic over the counter cat food. My search led me to Purina One Sensitive Systems. I purchased a small bag and fed a small amount to both my cats. They devoured it! I prayed and held my breath that my sick kitty would keep the food down. She did!! It has only been three days but, so far, she is doing great - no vomiting. The savings is phenomenal!!! I was paying 67.00 for an 8 pound bag of the prescription food. Thank you, Purina One!! June 30, 2016
Rated 5 out of 5 by Amazing food My cats had a big problem with throwing their food up and I wanted to find something that wasn't too pricey for them that they could hold down! I highly recommend this food for cats that have tummy problems! August 19, 2016
Rated 5 out of 5 by Purina One Sensitive Systems I have rescued over two dozen kittens and found homes for the babies and most of the adult parents. Those that now have chosen to remain with me I have had spayed and neutered and shots. Because of the variety of healthy of these adult cats I read up on and chose Purina One Sensitive Systems dry cat food. All have thrived on it and the Vet that I take them to gives them all a clean bill of health. July 31, 2016
Rated 5 out of 5 by No red dye I do not use any food that had red dye for any of my animals. Over 20 yrs ago my cats started throwing up their food quite a bit and figured out if was the dye and had to search and try cat foods that had no dyes and they liked. Now they are not throwing up and and looking healthy. I have also changed to Purina dog food and everyone I'd happy. July 27, 2016

    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.
