Rated 5 out of 5 by from Siberian Cat with Food Allergies loves Sensitive Systems! Smokey is a Siberian cat that we have had since he was 8 weeks old. For the first 12 months, he could not tolerate any food we gave him - soft or hard; fish, or meat or chicken. Chicken was recommended because it is so easily digested. The more chicken we gave him, the more diarrhea followed. Reading the labels on the cans, we discovered chicken is in almost every can whether it is fish or meat. Finally, one day a Vet Tech suggested Sensitive Systems. Not sure why we hadn't seen it on our own. We read the label. No chicken! Turkey is the primary ingredient. After a couple weeks of eating just Sensitive Systems, his system was just as normal as any other cat we've had (we've had nearly a dozen over the years). Now, he . . . and we . . . are happy campers!

Rated 5 out of 5 by from 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!

Rated 5 out of 5 by from A True Purina Fan I adopted my kitty Abby a little over s ago. She was the cutest little 8 week old kitten ever. It didn't take long after getting her home, set up, and comfortable to see that she wasn't just picky when it came to her food but she had a hard time keeping it down. After taking her to the vet many times and us trying her on many different perscribed foods that she refused did a vet tell us she has sensitive stomach and he handed us a sample of Purina Sensitive System Formula to try. I was extremely surprised until then every vet just kept writing us prescriptions for expensive foods you had to purchase at the vets office that Abby didn't like. After giving Abby the bowl of Purina it didn't take but a few seconds of her looking it over, giving it a few good smells that she immediately started eating it. This was the first time in the 2 months that we had her that she really liked the food she was eating. I was a little worried she wouldn't keep it down but she did. After about 2 weeks I was able to finally relax. Abby was still keeping the Purina down and still loving it. Today you would never guess by looking at her that she's 15 years old.She's healthy, happy, and full of energy. She truly is a special part of our family. We love her so much. She's the Best! I want to give a BIG Thank You to Purina, you're the Best!

Rated 5 out of 5 by from 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!

Rated 4 out of 5 by from 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 from This food really helped my cats I have 2 indoor cats and at times they were throwing up. One had dry skin really bad and was loosing her back hair. I switched to this food with the soft meow mix cups and they are all better. The one with the dry skin, she is all better and her hair is so soft. Her weight is even better. She has more energy and is even playing again. She will be 10 years old in July. The other cat wasn't all that sick...just threw up once in a while. The change in food was definitely a good fit for both of them.

Rated 5 out of 5 by from 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! ;-) ]

Rated 5 out of 5 by from Quality food My cats eat this all the time. Both have very sensitive systems and they have the least problems with this food. NOW FOR MY NEGATIVE COMMENT. I tried to download the coupon but my printer didn't print it and the system would not let me try to download it or print it again.

Rated 5 out of 5 by from Inflammatory bowel diseased cat Although our cat has episodes with IND, we've had many fewer with this food. Tried many others with no success and bloody emesis at times. When she gets sick now, it's infrequent and of very short duration. I can't help but think her daily nutrition is the reason.

Rated 5 out of 5 by from 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!!

Rated 5 out of 5 by from Life changing We rescued a cat a few months ago and he had a horrible problem with loose almost uncontrollable bowel movements. The vet treated him for all kinds of things and it was still happening, I found Purina One Sensitive Systems and not only does he love it but now he has normal bowel movements and it doesn't just "happen" wherever he is at the moment. We would all definitely recommend this brand of cat food to anyone that has a kitty family member with tummy issues.

Rated 5 out of 5 by from Excellent food I adopted 2 polydactyl (extra toes) kittens. Phoebe had constant diarrhea on every kitten food I tried. Found one that helped, but her sister, Daphne, is very picky and wouldn't eat it. Was getting ready to take her to the vet, but decided to try Purina for sensitivities first. In one day she had normal stool, and her picky sister loves it. So will be keeping them on this permanently. I am so glad, and I have 2 very happy kitties. Happy kitties-happy mommy.

Rated 5 out of 5 by from MY CATS PREFER PURINA ONE, BY FAR I've tried many brands of cat food, including the expensive foods from the Vet (which my cats refused to eat.) My cats love Purina One. We've tried all the flavors and they enjoy all of them. Originally I purchased Purina One because my cats cannot tolerate anything with red dye (it gives them diarrhea.) One of my cats was especially sensitive to the dye. So I started checking labels and Purina One is one of the few that doesn't contain that dye.

Rated 5 out of 5 by from Offers an alternative to other Purina cat foods; both dry and wet! We have several cats and have been feeding them NOTHING BUT Purina products. Some of our older "kitties" were having a little problem with one of Purina's newer formulas, so we tried the One products, both wet and dry, and after a short time ALL of them have changed for the better. We, and they are so pleased that Purina goes the extra mile to produce great animal products. Thank you all!Harriet CampbellBloomington, Illinois

Rated 5 out of 5 by from Keeps Tummies Happy We have 2 cats - one who will eat *just* about anything and one we call Miss Picky Pants. When I tried another brand, of course Lucy, the eat anything cat, scoffed it down. Maxine, on the other hand, wouldn't go near the bowl. And when they did eat it, BOY the gas they had was HORRIBLE! So, I went back to Purina ONE Sensitive Systems. They both love it and we no longer have any gassy issues! Keep up the great work Purina!

Rated 5 out of 5 by from Who wants to clean up cat puke? When my cat ate dry food first thing in the morning he would always throw some of it back up. I purchased Purina One Smartblend for sensitive systems for him and I was amazed from the very start at what a difference it made. He loves it and I am no longer cleaning up cat puke everyday. My other cats, who didn't have a problem love it also so I am now feeding it to all of them. Thank you Purina.

Rated 5 out of 5 by from Good Food for Cats We have been using the Purina One Smartblend Sensitive Systems Formula for a number of years. We are very happy with this brand for our 4 cats and they love it. It has helped a lot with our cats not upchucking after eating. We are very happy with this brand and will continue to use with our cats and any future cats we own.

Rated 5 out of 5 by from Keeps my older cat healthy Both of my cats have been eating a mix of Purina One Hairball formula and Purina One Sensitive Systems dry food. I took my 19 year old cat to the vet and had bloodwork, and I was told the labs are perfect, and to keep doing what I'm doing. I believe this food is a big contributor to my cats' overall health.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Only Cat Food I Will Feed My Cat (s) I have fed Purina One Sensitive Systems to my 12 yr old Viper Boy & was also the only food I ever fed our late Dakota Girl . It is honestly the only food that does / did not upset their stomachs ♡ Nothing but the best for my furbabies !

Rated 4 out of 5 by from 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!

Rated 5 out of 5 by from 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!!

Rated 5 out of 5 by from Great food for my elderly cat! We took in a 17 year old cat from a coworker of my wife. She was moving and could not take the cat with her. She gave us a bag of this food. Cat loves it and rarely has any type of digestive issues.
