My cats have been in Hills sensitive stomach chicken flavor for around 6 months now and very rarely get vomit anymore… highly recommend but it’s a bit pricier than cheap stuff. One bag gets me by around 3 months with 2 cats. (Largest bag)

I used to get a lot of vomit with my female cat who was eatting Made by Nacho beef flavor… I don’t think she likes beef but Hills hardly anymore vomit.

I use the Hill’s sensitive stomach formula, both dry and pouch. There’s a canned pate, but that isn’t quite as popular with my guy.

Hi! I think purina and Hill’s make dry food catered to more sensitive stomachs, just try searching it up

Have you tried the Pro Plan Sensitive Skin and Stomach? The chicken & rice was recommended by my vet for a cat with gastric issues, but if that's not working, maybe the other formula might.

Purina one dry works better for my sensitive stomach girl than pro plan dry. Purina One Sensitive Stomach is what she gets for dry. Pro plan turkey and giblets in gravy is the only wet she can have so far without diarrhea.

My sensitive tummy boy does really good on Hill’s Food sensitivities z/d + some KOHA wet food with one ingredient (usually rabbit). He had vomiting and diarrhea on and off for years, I tried an insane amount of different foods and now he is doing extremely well with the z/d!

Even if it doesn’t work, don’t give up! it might not be the solution for your cat but other food can work! It took me years to find a food for my cat that didn’t give him any issues.

Reveal chicken or tuna/shrimp. You’ll need EZ completer. I just boil meat at home or buy sushi grade fish for my cat.

Air dried Ziwi Peak for “dry food”

Just feed wet food without gums to see if that's the issue and add s.boulardii

Science diet sensitive stomach. Swear by it.

My boy has a very sensitive stomach and he's done well on the Go! wet foods that don't have chicken, beef, or grains. I feed the lamb and boar, salmon, and duck varieties. For dry food, I feed either Ziwi or Orijen, the fish variety, as most hard foods have one of his sensitivities. He now has solid stool and doesn't vomit all the time.

I found that this article has some good recommendations on what to buy for your cat. There's an option for kittens, adults, and seniors.

I switched to this because my cats were constantly hacking hairballs and puking up foamy matter. Now my youngest cat is puking her food up daily so I have to switch to something else

Maybe a limited ingredient food? Natural balance has a good selection. https://www.naturalbalanceinc.com/cat-recipes/limited-ingredient/?utm_source=google&utm_medium=cpc&utm_campaign={{campaign.name}}&utm_content={{adset.name}}&gad=1&gclid=CjwKCAjw-IWkBhBTEiwA2exyO_oCH4pPukvf49KHety-FSOxzGl1QRTgJ4dIoffrcf4r6U5swvUynBoC7EoQAvD_BwE

Limited ingredient food only uses 1 protein source. Many pets on them do great on them if they have food sensitivities.

My kitty has hills science diet for dried, and chopped fresh chicken meat. Commercial wet food does nit agree with her.

I've been feeding Royal Canin Sensitive (not RX) for a few months now and they rarely vomit now.

Have you checked in with your primary vet? Many brands make food for sensitive stomachs. Otherwise, you can try limited ingredient diets to see if there’s any particularly intolerant ingredient.

Royal Canin gastro moderate calorie is great for my cat with sensitive tummy issues. We get it from our Vet, and she’s doing great on it! There’s one called sensitive digestion as well.

We use Royal canin digestive when our girl has tummy troubles then swap her back to lean poached chicken for a day or so. It seems to settle her down

Hill's Science Diet, Royal Canin, Purina and Iams are all good.

Eight month old tabby, found in the woods at four-six weeks, for background.

We found out one of our cats was allergic/intolerant to chicken. Switched her to a fish-only food and no more tummy troubles!

Probiotics are a good idea. Our original vet gave us Purina FortiFlora when our kittens were on antibiotics. It helped.

We switched to Fera Pets brand from Chewy later on, simply because one of my cats didn't love the taste of the FortiFlora. They prefer that, and eat it sprinkled over their wet food without complaints.

I use, Nutramax Proviable Probiotics & Prebiotics Digestive Health Supplement for Dogs & Cats. I have an elderly male cat that needed help with loose stools and so far this has helped him. I found it on Chewy.

He may have an upset stomach.

Cerenia worked wonderfully for my boy. It's injectable or can be given orally either with pillshooter or dissolved in oral syringe. Break tablet in half, put pieces in oral syringe with warm water and shake vigorously to dissolve.

Got transdermal Mirtaz to put in his ear - Mirtaz is an appetite stimulant and mild nausea preventer. Cerenia is a step up from Mirtaz to treat nausea.

For treats I give Delectables Bisque 15yr+ Kidney Support Wet Cat Treats - Tuna & Chicken, 1.4 Ounce (Pack of 12) https://a.co/d/gQB0l0c or Hartz Delectables Stew Senior 15yrs+ Kidney support Wet Cat Treats, Chicken & Tuna, 1.4 Ounce (Pack of 12) https://a.co/d/7tPZVbl

The Stew has chunks of real meat, the Bisque has meat blended/ground up. They love them both though I have one cat that doesn't like the chunks of meat in the Stew (eats around them) but wolfs down the Bisque.

Perhaps you could use one of those to coat his Prescription food?

My guys seem to love Hill's i/d dry for sensitive digestive systems. The wet version they'll eat but less enthusiastically, they definitely prefer dry.

Pretty kitty!

You might check out the food data tables from the Tanya CKD website. There's info for both rx and non-rx foods. It explains on the page but the phosphorus level listed is often the primary driver in food selections. If his stomach does better with certain proteins you could look for varieties of those flavors with lower phosphorus. If he's in early stages then selecting some lower phosphorus foods that his tummy agrees with might be all he needs right now.

I’m just starting out with my cat too. Are you going onto prescription diet? Mine doesn’t really like any of the prescription diets so I’m doing a slow transition. He seems to like the best Hills (if he had to pick I guess lol). I’d see if you can get written prescriptions then try different ones. Some my cat smelled and was like “nope.” Others he took a bite or lick or two but then walked away “this is not what I ordered.” So I’ve started doing the transition method to trick him into it.

I’d also talk to your vet but sensitive stomach can be totally related to kidney disease so getting him on the prescriptions might help. I also heard they can have Pepcid ac but I need to ask more questions about it. Actually found this sub to look at peoples interactions with slipper elm bark but still doing research.
