Sensitive Systems

Purina ONE® SMARTBlend® Sensitive Systems Formula is rated 4.8 out of 5 by 208.
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 Monkey B. Kittee loves the taste! We were having some vomiting problems until I switched to Purina One Sensitive Systems for her. It worked almost immediately, like magic. Monkey Bee simply loves the taste and texture.

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 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 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 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 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 Older cat 1 of my 5 cats are 12 years old and started having trouble digesting her food. She would throw up all day. Switched to purinaone and she feels so much better. Highly recommend for older cats.

Rated 5 out of 5 by from Sensitive Systems is the best for my girl! I inherited my Libby girl from my mom and found that she vomited a lot after eating. After several vet visits, my vet recommended Sensitive Systems. Best thing ever for my girl!

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 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 Good for Digestive Issues Since he was very young, my cat has had a sensitive stomach and digestive issues. I won't go into detail, but he had significant issues. Frequent vet trips, medicine and trying different foods would help the problem a bit, but the one other food that really helped was an expensive prescription food that I had to order...then I tried this and it worked wonderfully!! My three other cats love it, my sensitive-belly cat loves it and I could not be happier. I felt so bad for him and I am thrilled that not only is this product a reasonable price, but this company cared enough about animals to develop such a product.

Rated 5 out of 5 by from losing hair from food allergy -- RESOLVED we were using an indoor advantage cat food for Chelsea and she started pulling her hair out in clumps after a year. We took her to the vet and figured out it was her food. we switched to sensative systems and her hair is now growing back in and she no longer has the issues of pulling her hair out or itchy spots from her allergy. Chelsea had pulled out nearly 1/4 of her hair from her tail to her front shoulders on her trunk. She was also throwing up frequently. I guess animals are like humans and food allergies can happen after a while. Thanks for the food that works so great on her and she loves eating it.

Rated 5 out of 5 by from Sensitive System I have 3 Kitties and they all have been eating the Purina One Sensitive System for over 2 years. I had a problem with my 5 yrs old Cat vomiting after he ate and my Vet put him on the Heinz Diet after 2 months he was still getting sick so I switched them all to the Purina One Brand and within 1 month he was no longer getting sick all 3 love it and when I got my last kitty I was feedind her Purina One Kitten. I highly recommend it to everyone I just wish you would have coupons for it All I ever get is ones that are for Purina Cat Chow Brands If you could put more in the papers that would be great

Rated 4 out of 5 by from Pur fect My cat has a very bad stomach. She is sensitive to everything. She will throw up every brand but once I tried the purina one it did her well. She has been on it for two years now and there is no issues with it. Also now that I got a kitten she is also eating this food mixed with her kitten food and believe it or not that is the only way my kitten would eat the dry food. Before I was giving her plain kitten food and she would not eat it. I am glad I tried the purina one brand. I just wish I can receive more coupons though.

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 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 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 Purina One Sensitive Transition I have four cats that tend to have digestive issues. The switch to Purina One Sensitive was recommended by my local SPCA. I slowly transitioned their food, along with small amounts of pureed pumpkin, and have had great results. I am almost to the point of weaning off the pumpkin and solely feeding the Purina One Sensitive. I thank you and my carpets thank you!

Rated 5 out of 5 by from Favored food if my cats I feed both canned and Purina One kibble dry food to my three cats. This is the only kibble food my cats will eat. One of my cats prefers kibble over canned and this is his favorite brand. The one who eats just the Purina One kibble has the best coat and looks the healthiest of the three cats. They seem to like the Turkey and Chicken flavors the best.

Rated 5 out of 5 by from sesitive stomach My cat Mylie has a sensitive stomach. If she isn't fed food like Purina One for Sensitive Stomachs food she will have diarreha bad. She has had it since she was a kitten. She loves it and my other cats do too. I do let some of the other cats have some once in a while but its mostly for my cat and she loves it and it helps her with her problems.

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 Excellent product that my cat loves! I have a picky outdoor cat who will leave dish half full until I switch back to Purina products(if i buy something else on sale). She loved this sensitive formula! Prefers chicken/turkey ones over fish flavors. Doesnt get sick& eats it all up! Thank you Purina for the free sample& coupons!

Rated 5 out of 5 by from Settled cat's stomach I was unable to print the coupon but I've used the Sensitive Systems in the past and my cat has stopped throwing up! I actually mixed it with the cat food I had on hand so as not to waste it, but it worked. Would like to continue using it. Could you mail me a coupon? Thanks!

Rated 5 out of 5 by from Cats love it! Not only do my cats love it, my oldest has severe issues with a sensitive tummy. She has thrown up most of the super expensive specialty brands but very seldom has issues with Purina One! Thank you for delivering such a great product at such a reasonable price!

Rated 5 out of 5 by from Digestive Issues Resolved I have four rescue cats and within a month of using Purina One Sensitive Systems, all four have shiny and soft coats, bright eyes and no vomiting/digesting issues. They like the smaller nuggets. Thank you for such a great product.

Rated 5 out of 5 by from Helps ease tummy issues My 2 cats occasionally have an upset stomach and vomit when I feed them dry food. My vet recommended Sensitive Systems, so I bought some. My cats seem to have fewer digestive upsets, and they enjoy the taste of this blend.
