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 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 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 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 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 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 Better health & they love it. My cats, all 13 of them, had constant diarrhea and occasional unexplained vomiting. We tried various brands & formulas, as well as supplements without success. After giving it a trial run we've since switched them completely to the Purina One Sensitive System formula and they're all doing so much better! Their stool is as it should be, they all have more energy, seem happier and healthier overall, and aren't soiling the floor any longer. It's more expensive than what we used to buy, but the results are well worth the extra cost. September 22, 2015
Rated 5 out of 5 by Healthier skin and fur I,convinced boyfriend to change to. this as his cat was rubbing area above eyes raw. I had read sometimes allergies and skin issues cause this behavior. After one week above one eye completely filled in with fur and two weeks second eye coming along and fur thicker and has some shine..cat seems happier. Ten yr old cat. I've had three dogs on Purina one after change from expensive brands and it's kept them going . September 22, 2015

I wasnt able to print a coupon, but glad I did try it anyway! September 27, 2015
Rated 5 out of 5 by Purina for Sensitive Stomachs My 5 year old cat has had stomach problems for years when eating regular Purina cat chow. After I switched to Purina for Sensitive stomachs, she has not been vomiting food up as often and she has gained weight. Thank you Purina! September 26, 2015
Rated 5 out of 5 by Simply amazing! I have one female 5 year old adult cat who was constantly getting sick every time after she ate. I slowly introduced her to this sensitive system food and at first while the other food was still mixed in she was still getting sick but once she was eating 100% of the sensitive system she has stopped throwing up. I know she's happy! She's more vibrant and energetic and I'm happy cause it's making her a happier healthier cat!! September 15, 2015
Rated 5 out of 5 by Purina 1 sensitive cat food I adopted my cat from one of the homeless cats I feed everyday & noticed she was having a bit of trouble on food I was feeding him so I switched to purina1 for sensitive cats right away & noticed a Wonderful difference, so I am very happy with your cat food sincerely Ramona & my no longer homeless cat Prince ( My Prince Charming ) August 30, 2015
Rated 5 out of 5 by Awesome Purina One For Sensitive Stomachs I have two older cats that were throwing up almost every day. I started the Purina One. They loved it and the vomiting stopped immediately. Both cats have been dong great ever since. Thanks for this excellent product. August 28, 2015
Rated 5 out of 5 by Natural product My cats seem to like it & I like the fact that there NO dues in it! August 10, 2015
Rated 5 out of 5 by Cat was vomiting Cat was vomiting too much. Took her to the vet and tried Purina Sensitive formula - has only threw up 1 time in over 2 weeks. She was throwing up at least 4-5 times a week before this. Definitely worked for us! August 5, 2015
Rated 5 out of 5 by Helped my older cat. I started using Purina One Sensitive System for an older cat several years ago. It improved her digestion as well as the odor of her stool. She is now gone but I continue to use it for the cat we now have. August 1, 2015
Rated 5 out of 5 by Years feeding Purina Cat Chows We have had cats for most of our 36 years of marriage and have fed Purina most of those years. At first we fed other brands, but we were not happy with the results. We then switched to Purina and our cats are happy and healthy. We are especially happy with the Sensitive Systems chow. We have a long-hair and she can have digestive difficulties. This food helps her so much! July 11, 2015
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 PLEASED THE PICKY Two years ago, I relocated and had to have my grandmother watch my cat for two months during the transition. Being a grandmother, she babied him just like a grandchild. She boiled chicken and mildly seasoned it for him and would portion out his individual servings and deliver his homemade meals like clockwork. After getting him back home, I have had to still boil chicken and mix with dry food to even get him to look at it. When I switched to Purina One Special Blend, I haven't had to add any chicken. He absolutely loves it! It's a relief for me now that I don't have to specially pre-boil and specia season chicken for every meal and I know he's getting the nutrition he needs. I would recommend this product to any cat owner. After trying Purina One Special Blend and my cat liked it so much, I've switched my four dogs to Purina One as well. April 4, 2015
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. June 27, 2015
Rated 5 out of 5 by What a relief! No More Smelly Cat! I took in a feral male cat who has now had his vaccinations and been neutered. I was feeding him a well-known brand of cat food, but he had such a problem with gas and diarrhea that I could not let him stay in the house. I switched to Purina One for Sensitive Systems, and now there is no more problem. Another feral cat I feed was losing his hair, but now on this food, his coat looks quite healthy. July 6, 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 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 better my cat doesn't throw up when she eats the sensitive formula July 5, 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 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
