Best Novel Protein Blend Cat Food for Sensitive Stomachs-Iams Proactive Health Sensitive Stomach Adult Cat Food

Our Rating: (4.5/5)

Cats with sensitive stomachs tend to avoid eating if they begin to experience abdominal pain, diarrhea, or vomiting shortly after eating. Cats are smart and will associate their pain and discomfort with cat litter if they’ve experienced discomfort when using their litter box, or they’ll associate it with what they’ve eaten. This is why a cat with a sensitive stomach will often eliminate outside of the litter box. To prevent a cat from inappropriately eliminating outside of their litter box in the future, and to soothe an upset stomach, people need to look for a product that contains ingredients that will be gentle on a feline’s stomach.

In most cases, animal protein can be to blame for sensitive stomachs and GI upset. If your kitty is refusing to touch their food and you’ve noticed that they can no longer tolerate a standard pet food, then this formula by Iams may be just what your kitty needs.

Best Cat Food for Sensitive Stomach Buyer’s Guide

As a cat owner, you know the importance of choosing a product that your felines will find appealing, but certain ingredients can trigger digestive upset in some cats. When you’re doing your research, checking out product labels for each type of sensitive stomach cat food you come across, you’ll want to be careful about the types of proteins it contains, in addition to how much fat and carbs there are per serving. If you have a cat with allergies, then you’ll need to be extra careful concerning which formulas you try. With seniors, a low protein diet is often the best option since a higher protein formula can be very hard on their kidneys.

I’ve put together some great information that shows you exactly how to skim through a product’s ingredients list so you can quickly narrow down your choices and find a product that will work well for your pet and offer the type of flavor they’re sure to love.

Symptoms of Food Allergies in Cats

cat food for sensitive stomach

Allergies can be very tricky to treat, since you’re not sure what ingredient is causing an allergic reaction. In some cases, it can be grains, in others, protein is to blame.

Food allergies often present themselves in the form of skin issues, chronic scratching, and cats that are constantly grooming. If a cat is having an allergic reaction to their pet food, they may groom themselves so much that they break the skin, creating sores called hot spots.

Symptoms of Food Intolerance in Cats

Food intolerance is not the same thing as a food allergy. If your cat is struggling with food intolerance, they may have chronic diarrhea, upset stomach, constipation, bloody stool from defecating so much, a lack of appetite, bloating, or vomiting. Older cats are prone to developing a food intolerance because many pet foods contain too much fat, which can upset their stomachs, or the formula is too high in protein, which is very hard on their kidneys.

How Food Intolerance is Diagnosed in Cats

A food intolerance can be more difficult to diagnose, since it cannot be tested for like a food allergy. In most cases, a veterinarian will place a cat on a food trial for two to three months. During a food trial, the cat must not be given any treats or table scraps. If any of their past symptoms clear up when they’re on a food trial, then an allergy may be to blame. The diet will consist of a type of protein a cat has never had before, such as venison or rabbit. Once the trial is complete, the vet will place the cat on their old pet food. If symptoms appear again, it’s safe to say that their pet food was the culprit.

In other cases, the vet will require the owner to make a very simple homemade pet food during the trial that consists of one to two ingredients, with a new ingredient added each week. It often begins with some ground venison and rice for a week or two, with a new ingredient, such as oats or a new protein added. During this time, it’s the owner’s job to note how their cat responds to the diet, such as episodes of vomiting, skin rashes, or diarrhea. If any symptoms appear after adding a new ingredient, the ingredient will be removed from their diet.

A vet may determine that the cause of stomach upset is due to a diet that’s too high in fat or protein, in which case, they will recommend a low fat, and/or a low protein diet. This is a common issue with seniors, which is why most products that are designed for seniors have a lower calorie content, lower fat, and lower protein.

Choose a High-Quality Cat Food

Fillers, additives, and preservatives can also cause stomach upset. Only use a formula that contains all natural ingredients such as oats, whole grains, veggies, novel proteins, and the right balance of vitamins and minerals.

Try a New Protein

Cats are used to foods that contain chicken, certain types of fish, or beef. Your cat may have a chicken intolerance or allergy, so try a new formula that contains a different type of protein and steer clear of chicken and beef. Foods that contain salmon, herring, venison, or rabbit, are all great options.

Turkey is also a great alternative and tends to be easier on the stomach.

Low-Fat Food Options

Older cats don’t have the same type of high protein needs that a younger cat does, and they don’t require the same high calorie diet. If you have a cat over the age of seven who is not very active, then they may benefit from a diet that’s low in fat. A low fat diet is also gentler on the stomach and will not cause vomiting, regurgitation, or diarrhea like some types of high fat diets can.


When I mentioned food allergies earlier, I briefly touched on grains. While it’s more common for a pet to develop food allergies to a protein source, some cats can also develop a grain allergy. Some pet owners have found it helpful to switch to a grain-free pet food. This type of diet closely mimics what a cat would eat in nature by ditching the corn filler that’s found in most commercial pet foods, as well as any other grain-based ingredients. While grains aren’t terrible for pets, they should be given in moderation, and definitely should not be the main ingredients in cat food. A cat didn’t survive on corn in the wild, so why should their diet at home contain such high portions? In many cases, corn is added as a filler.

Gradually Switch to a Sensitive Stomach Diet

If you’ve decided your pet’s high protein, high fat, high carb diet is the culprit behind their digestive issues, then you need to gradually switch from their standard pet food to one that’s formulated for sensitive stomachs. Making the switch immediately will only lead to more stomach issues. The process should be gradual. Begin by reducing their regular kibble by ten percent and adding ten percent of the new food. You’ll do this slowly, reducing their old food by ten percent, and increasing the percentage of their new food, every two to three days or as tolerated. This process can take a week or two, but it’s definitely worth it and will not be a shock to your pet’s digestive system.

What Foods to Avoid Feeding a Cat with a Sensitive Stomach

eating cat food for sensitive stomach

Once you’ve pinpointed the foods or ingredients in your cat’s diet that’re causing problems, then you’ll need to carefully read pet food labels to make sure you avoid these offending ingredients. Some felines can’t stomach cat foods with specific ingredients, such as wheat, soy, corn, chicken, or beef. By keeping a food diary of what ingredients seem to cause digestive problems, you can prevent episodes of diarrhea or vomiting in the future. Always refer to this list when you’re researching which formulas are right for your cat.

A cat may not be able to tolerate pet food formulas that contain chicken, but some are so sensitive that it may be a single additive or coloring that can cause all sorts of skin and digestive issues.

Look for Low Protein Cat Food for Seniors

If your cat is over the age of seven, they are considered a senior. Seniors can have trouble eating cat food that’s too high in protein. Cats normally follow a high protein diet, but as they age, their body is not able to process protein as efficiently. Higher protein can also be hard on the kidneys. Additionally, older cats are not as active as young adults and don’t have the same type of high protein needs. Cat foods designed for seniors with sensitive stomachs will have a lower protein content.

Follow a Bland Diet to Rule Out Certain Ingredients

When a cat has this level of sensitivity, they will definitely benefit from a bland trial diet, which often consists of a grain and a protein. This can help pet owners determine if their intolerance is due to a common food or ingredients that are added during the manufacturing process. Of course, if you have serious concerns about your pet’s health and their diet, speak with your vet. Your cat’s vet can help you discover the cause of your cat’s health problems and give you advice on how to proceed.

Find Limited Ingredient Cat Food

In terms of choosing a new commercial pet food, dog owners have it much easier since limited ingredient dog food works to eliminate all the unnecessary ingredients. Cat food manufacturers have wizened up and have begun to produce these sensitive stomach limited ingredient formulas, but they’re still not as common or as readily available as limited ingredient formulas for dogs.

Stop Giving Your Cat Treats

During this time, while you’re transitioning your pet to a new food, avoid giving treats. You may need to stop giving your cat treats indefinitely, especially if they’re older and have stomach issues due to treats that are too high in fat or protein. Just a handful of these rich treats can upset their stomach. Treats should never make up more than ten percent of a cat’s diet. Going overboard with treats, especially with an older cat, can cause a whole host of problems including diarrhea and vomiting.

How to Treat Upset Stomach in Cats

If you’ve been struggling with finding foods that your cat can tolerate, without vomiting or diarrhea, there are some things you can do, in addition to switching their pet food to a formula that’s specifically designed for cats with sensitive stomachs.

  • Cats have a tendency to eat large portions of food quickly, which can upset their stomachs. Many people free feed their cats, allowing them to graze all day long. While this may be perfectly fine for some cats, others need to be given their food in smaller portions, a few times a day. This is especially true for cats who often experience diarrhea, regurgitating, or vomiting after eating.
  • Keep a close eye on your pet’s eating habits. As you make the transition from their old pet food to a sensitive stomach formula, you should also make the change to smaller portions.
  • Hairballs can also be a big problem and one that can cause vomiting and constipation, if not addressed. If you have a long-haired cat that suffers from chronic hairballs, the best thing you can do, aside from switching to the best cat food that’s specially formulated to help reduce hairballs, is brush your cat daily. Some cats love being brushed, and others will make a run for it as soon as they see their brush. But brushing out a cat with a long coat is key to minimizing hairballs, which, in turn, can help to reduce episodes of stomach upset, diarrhea, bloating, and constipation. Long haired cats and seniors tend to be more susceptible to hairballs compared to cats with short coats.
  • If your cat eats dry cat food, then dehydration can also be part of the problem. Make sure you have a few bowls of fresh water left out and change the water daily. Cats can be very fickle about their water. The water dish should not be placed in a high traffic area or near their food or litter box.

Frequently Asked Questions

What to Feed Cats with Digestive Problems?

If your cat begins experiencing digestive problems out of nowhere, it may require a trip to the vet. Until you see the vet, change their diet to a bland one and prepare white rice mixed with a little boiled chicken. Avoid giving them their regular pet food or any treats until they see their vet.

How Do you Know if Your Cat has a Sensitive Stomach?

Cats can get an upset stomach for many reasons, whether they’ve been playing in the yard and eaten something they shouldn’t have, their pet food is too high in fat or protein, they have a long coat and are prone to hairballs, or another type of underlying conditions such as liver failure or diabetes. Visiting the vet will help you pinpoint the cause and make the appropriate changes to their diet so you can find the best cat food for your furry friend.

Is Wet or Dry Cat Food Easier to Digest?

No, but it does offer some health benefits that kibble doesn’t. It contains high levels of moisture, so your cat can get a large percentage of their hydration from their food. If your cat is prone to dehydration, then switching to a wet pet food can be a good solution and one that promotes bowel regularity as well.

What Causes Digestive Problems in Cats?

Traditional kibble is often too high in carbs, fat, or protein, which can cause digestive upset. Cat foods for sensitive stomachs will often feature a low protein, low fat, and low carb diet, which is much gentler on an older cat’s digestive tract.  Other causes of digestive upset can be due to your feline eating toxic plants or foreign objects, hairballs, or an underlying health condition such as hyperthyroidism.

Final Thoughts

The best cat foods for sensitive stomachs will have a lower protein content, should be free from additives and fillers, and should contain a novel protein. Cats that have longer coats may require a sensitive stomach formula that can help to prevent hairballs in the future, while seniors with stomach issues should be placed on a formula that’s specifically designed to meet their nutritional needs. This guide and the products I’ve included here can help you find the best cat food that will work well for your feline, one that will not trigger an allergic reaction or adverse reaction, or include foods that can cause stomach upset. With a little time and patience, you can find the best cat food for your pet, one that comes loaded with important vitamins, minerals, and other nutrients that are gentle and designed to help your cat thrive.
