Signs Your Cat Has A Sensitive Stomach

close photo Red-headed sick cat

It is usual for your little feline friend to end up swallowing their hair during grooming accidentally and coughing up the hairball. But, if you notice them experiencing regular upsets, vomiting post meals, or having allergic skin, it is merely an indication that your cat is unwell.

Some of the most common signs of a sensitive stomach include constipation, diarrhea, vomiting, changes in stools, itching, skin issues, poor condition of coat, sudden weight loss, increase in thirst, etc.

In case your feline is experiencing any of these sudden changes, then you should immediately head to the vet, especially if you feel that these signs are chronic and can be a potential threat.

These issues are most likely the outcome of food allergies, so you should look for the best cat food with a less allergenic formulation suitable for the specific case and help your cat overcome the problem. 

Now, let's explore, in more detail, some of the most common symptoms of sensitive stomachs in cats. Once you notice any of these symptoms, seek a vet's help, as there could be other more or less serious causes of the problems.


The fact that your cat vomits after eating could be a sign that there was something wrong with their meal. It might also indicate that they ate too much at once, which causes them to experience indigestion. In addition, it could even point toward a digestive disorder such as gastritisp [1].

If your cat has been vomiting frequently and consistently over several days or weeks, then it's time to take them in for a vet examination to rule out any underlying health issues before deciding on what kind of diet would be most suitable for your pet.

Not Eating/Off Food

A healthy cat requires proper nutrition. So, if they stop eating altogether, then this is definitely not normal behavior. You must make sure that you feed your cat properly every day. Also, ensure that you give him/her enough water throughout the day.

Cats with sensitive stomachs may refuse to eat anything at all; this could be because of one or more reasons:

  1. Your cat may have an underlying medical condition that requires a special diet. For example, cats with kidney disease need special diets as they can develop urinary tract infections [2]
  2. They may just want to avoid certain foods due to bad memories associated with those particular items. 
  3. Perhaps they simply don't enjoy the taste of the food anymore?


Another sign of a sensitive stomach is frequent bouts of loose stool. Cats usually do not get diarrheal diseases unless they consume spoiled food or ingest toxic substances. However, sometimes, a change in dietary habits can cause diarrhea. 

It is important to note that diarrhea does not necessarily imply that your cat suffers from gastrointestinal problems. Sometimes, it could simply be caused by stress or anxiety.

Excessive Gas

When your cat experiences excessive gas, excess air is trapped inside its intestines. He/She feels bloated and uncomfortable and won't be able to move around freely. This may indicate some kind of food allergy such as dairy food intolerance (or even spoiled food, too much red meat, etc.). Your vet will be the best to pinpoint the source of the problem and provide solutions to fix it.

Always remember that you should always seek the advice of your veterinarian or other qualified animal healthcare provider with any questions you may have regarding a medical or behavioral condition that your cat may suffer from.

What To Look For In Cat Food For Sensitive Stomachs?

cat food for sensitive stomach

If you feed your cat healthy food but they still seem to suffer from indigestion, you should consider cat food for sensitive stomachs. Here are some tips on what to look for in that type of food:

1) Look for high-quality ingredients. Ingredients used in commercial diets may not always be safe for human consumption. Therefore, they shouldn't necessarily be fed to animals either. Some examples of low-quality ingredients include corn syrup solids, artificial colors, flavors, preservatives, fillers, and so forth. High-quality ingredients will contain only wholesome natural substances found in nature.

2) Avoid any ingredient that contains wheat flour. Wheat flour is known to trigger allergies in cats.

3) Make sure that the protein content is adequate. Ideally, it must be from a single animal source. Protein helps keep the body strong and healthy. Unfortunately, most commercially prepared cat foods to fall short when it comes to providing enough protein. 

4) Check out the fat content. Fat provides energy to the body. However, too much fat can actually slow down metabolism. As a result, the animal tends to gain weight. On the flip side, too little fat means that the animal doesn't receive sufficient amounts of healthy fats like the Omega fatty acids needed for proper growth and development.

5) Be wary of additives. Many manufacturers add things like salt, sugar, artificial sweeteners, flavorings, colorants, antioxidants, vitamins, minerals, probiotics, enzymes, prebiotic fiber, omega 3 oils, and others into their products. Check to make sure the food contains more beneficial supplements like prebiotics, probiotics, etc., and no artificial additives or sweeteners.

6) The food must also contain carbohydrates that are easily digestible.

Types Of Hypoallergenic Diets For Cats

good cat food for sensitive stomach

Hypoallergenic diets for cats don't contain any ingredients that are known to trigger cat food allergies. Not enough studies have been carried out on this topic, but it is known and proven that chicken, fish, beef, dairy products, wheat flour, etc., are ingredients that are most commonly linked to cat food allergies.

Hypoallergenic diets contain a single source of protein such as venison, duck, or lamb. They also avoid using any ingredients that could be potential allergens. 

There are many types of hypoallergenic diets for cats available today. In terms of protein content, the diet can either include hydrolyzed proteins that have been broken so much that the body doesn't recognize the allergens inside or novel proteins based on duck or venison.

There is another category of limited ingredient food that contains fewer ingredients than regular diets which can help identify what food your cat is sensitive to and avoid.

These diets vary based on the specific needs of each individual cat. For example, one diet might work well for an adult male while another would suit a senior female better.

That's why it's very important to consult with your veterinarian before making changes to your cat's diet. He/She knows exactly how different breeds react differently to certain nutrients and other dietary components.

Here are just a few common hypoallergenic cat diets:

  • Chicken & Rice Diet - This is a basic hypoallergenic diet made primarily of ground chicken meat mixed with rice. It has fewer calories than some other options so it may help reduce obesity in overweight cats.
  • Duck & Potato Diet - Made up mostly of ground duck meat combined with potatoes, this diet is low-calorie and high in protein. It's often recommended for older cats who need extra nutrition.
  • Venison & Potato Diet - A combination of ground venison and potato, this diet is similar to the previous option except that there's less poultry included.
  • Salmon & Potato Diet - Unlike the previous two diets mentioned above, this one includes salmon instead of chicken. It's lower in sodium than the first three diets listed here.

Most Common Causes Of A Sensitive Stomach For Cats

There are many causes of sensitive stomachs in cats. It is important to have an idea about those causes to recognize the condition if your pet develops it.

This doesn't mean the condition can be treated at home because the veterinarian is the only qualified person that can diagnose the issue and suggest treatments.

Here is a short video (1 minute 47 seconds) video from Dr. Lauren Samet sharing actionable tips that may help Caring for a Cat with food allergies problems

Let's now explore some of the very common causes.

Food Intolerance

Usually, cats can have food allergies between the ages of 2 and 6. If your cat eats well but still gets sick, chances are they have developed a sensitivity to specific ingredients found in commercial dry kibble.

These include wheat gluten, corn syrup solids, soy protein concentrate, artificial flavors, preservatives, colors, fillers, antibiotics, hormones, growth promoters, and other additives.

In addition, some cats can be allergic to specific types of foods like dairy products, fish, meat, chicken, etc. The good news is that these sensitivities can often be reversed through careful elimination trials.

Best cat food for sensitive stomach


Cats love grooming and chewing on their fur. Unfortunately, when they chew on their coats, they swallow small pieces of hair which eventually end up in their digestive system.

Most of that hair goes through the digestive system without problems, but sometimes a hairball is formed in the stomach and most commonly, the cat is able to vomit the hairball. Sometimes, however, the cat cannot regurgitate the hairball and will need a veterinarian's assistance.

When you notice your cat having trouble breathing while lying down, vomiting repeatedly, or experiencing abdominal pain, then maybe something is wrong with their digestion. 

This problem is more common with long-haired cat breeds such as Maine coons and Persians or cats that excessively groom themselves as they are more likely to swallow a lot of hair.

Apart from the risks associated with hairballs, grooming habits can also shed light on a cat's skin condition. Over-grooming or compulsive grooming, in particular, can be a sign of skin discomfort and might lead to issues like dandruff. If you notice your cat's coat looking lackluster with visible white flakes, it might be time to investigate further. Learn how you can relieve your furry friend's skin troubles by learning about why your cat has dandruff and how to get rid of It.

Eating Rubbish

Cats eat everything! They don't discriminate against what they put into their mouths. That includes garbage, dirt, grass clippings, leaves, sticks, paper, plastic bags, wrappers, toys, shoes, socks, clothing, bedding, furniture, carpeting, etc.

All this stuff ends up in their digestive tract; In fact, studies show that even healthy adult cats consume more than 10 pounds of waste per year. This could cause infections in the digestive system and lead to a sensitive stomach.

Some Types Of Food

The types of food that most commonly cause cats to have a sensitive stomach and allergies include fish, meat, chicken, and dairy products.

Also, foods rich in fiber or containing yeast are likely to cause digestive problems such as excessive gas. 

Moreover, red meat and cow liver are good for cats only if consumed moderately; these contain a lot of protein and vitamins, but a serious condition of vitamin A toxicity can be caused which affects the cat's bones.

In a nutshell, there are plenty of human foods that cats can eat [6] without problems, but some should be avoided because they can affect their digestive system or even be toxic or fatal - such as alcohol and coffee.

Eating too Fast

Cats do not digest food very quickly. It takes them about 30 minutes to an hour to finish eating. Therefore, feeding your cat at mealtime may result in them consuming large amounts of air during each bite.

As a consequence, they may experience indigestion from swallowing too much air. To avoid this problem, feed your cat slowly so that they do not inhale any air before finishing their meals.

Eating too fast could lead to simple problems like vomiting, but in the long term, it can also lead to more severe issues such as feline diabetes [7] (also known as diabetes mellitus) or arthritis [8].

Related: How Much Should Cats Eat?

Overeating on Portion Size

Cats usually require a minimum of two full-sized meals daily. However, many owners mistakenly believe that giving one big meal instead of two smaller ones makes better nutrition available to their pets.

This is a common mistake that could lead to the cat having a sensitive stomach because of the amount of food that the stomach has to digest at once. 

To avoid this problem, make sure that your cat has many smaller portions of food instead of a larger one every day. In addition, the average daily nutritional value should be limited to between 24 and 35 calories per pound.

Infection, Disease, & Illness

Sensitive stomachs for cats can also be a symptom of some underlying health problems and infections. These include Gastritis [9], kidney diseases, inflammatory bowel disease [10] (IBD), Pancreatitis [11] (Pancreas inflammation), etc. These need to be treated as fast as possible by a veterinarian.

Age-related changes

As we age, our bodies change over time. For example, older people tend to lose muscle mass and become less active. Consequently, it becomes harder for us to chew and swallow properly.

Cats are no different. They get old just like humans do. Therefore, when you see your pet getting slower and losing weight, it's probably due to aging.

If your cat starts showing signs of being sickly, lethargic, or experiencing other symptoms related to poor digestion, then it might be wise to take them to the vet right away.

Swapping Dry and Wet Foods on a Daily Basis

Cats don't like change at all, especially with something important to them, such as food. If a pet owner needs to change their cat's diet (be it dry or wet food), it should be done gradually over the span of 7 to 10 days.

It is preferable to introduce the new food with a 25% portion the first time and increase the percentage by 10% a day until the food is totally switched.

If the food type is swapped too fast or too often, this can cause the cat to have a sensitive stomach because the cat's sensitive digestive system won't be able to adapt to the swift or constant diet changes.


Parasites are another major cause of sensitive stomachs in cats. Parasite infestation causes irritation and swelling around the mouth area, which leads to difficulty chewing and swallowing.

In addition, parasites can block up the intestines causing diarrhea or constipation. Therefore, a parasite treatment plan must be followed carefully if there is a possibility of infection. 

Examples of these parasites include roundworms [12], heartworms [13], tapeworms [14], and hookworms [15]. Each of these categories includes many types of parasites, some of which can be life-threatening to the pet. They all cause digestive problems.

What Brand Of Cat Food Is Best For A Sensitive Stomach And Most Nutritious?

cat food brands

This is a tricky question to answer. It all depends on the individual cat and the owner. What works for one cat will not necessarily work for another. The problems, as well as the needs, vary from one cat to another.

What To Avoid Feeding A Cat With A Sensitive Stomach?

If you own a cat that has a sensitive stomach, you have to avoid giving him/her the types of food that are known to trigger allergies or digestive problems in cats. These are the foods to avoid so as to keep your feline friend in good health.

Raw Fish

Fish contains high amounts of protein and fat, both of which are essential nutrients. However, it's important to note that fish contain mercury, especially large predatory species such as tuna, swordfish, shark, king mackerel, marlin, salmon, cod, halibut, barracuda, and tilefish.

Exposure to higher levels of mercury can cause serious neurological problems and walking difficulties for cats because of "mercury poisoning". Also, raw fish may contain more bacteria and cause food poisoning. It also includes an enzyme that destroys an essential B vitamin called "Thiamine".

Raw eggs

Eggs are an excellent source of protein and other vital nutrients. However, it's very risky to feed raw egg yolks to kittens due to the risk of salmonella infection.

This could lead to severe diarrhea, vomiting, dehydration, fever, lethargy, weakness, coma, or even death. If your kitten gets infected by Salmonella, there is no cure except antibiotics.

Moreover, raw eggs can contain e.coli and Avidin and can cause gastrointestinal problems. Luckily all those bacteria can be eliminated if the eggs are cooked. 

Chives and Onions

In addition to leeks and garlic, chives and onions are very toxic to cats (and dogs too). This is because they contain substances similar to histamines that irritate the lining of the intestines, causing inflammation and ulcers.

In some cases, this leads to bleeding inside the body. Also, onion skins contain sulfur compounds that can damage liver and brain cells. The same thing applies to garlic cloves.


Cats love bones, but unfortunately, most people don't realize how dangerous they can be. Even if they may contain many nutrients that help improve the pet's teeth, bones and gum, bones must be avoided altogether for a cat with a sensitive stomach.

Cooked bones can break and cause choking or fatal internal injuries while eating too many raw bones can cause constipation or even blockage.

Fatty Foods

It's not recommended to give fatty foods to any animal, including cats. Both cooked and raw fat are likely to cause intestinal problems and lead to diarrhea and vomiting for a normal healthy cat. The consequences can be more serious for a cat with a sensitive stomach.


Dairy products are not toxic to cats, but they are still not recommended. If eaten in large amounts, dairy will cause an upset stomach accompanied by vomiting and diarrhea or even lead to obesity. Of course, the results can be much worse with a sensitive stomach.

Tips On How To Introduce A Sensitive Cat Food Diet

With cats, any type of change must be gradual. They are creatures that don't like sudden surprises or change, and food is no exception. If the transition to the new sensitive stomach diet is too swift, the cat may have an upset stomach.

You need to be patient during the food transition period. It should take some time between 7 and 10 days. You'll need to monitor your cat closely during this period to make sure he/she doesn't get dehydrated, underweight, or experience digestive issues.

You might want to start out by slowly increasing the percentage of the new diet over several days rather than doing it overnight.

For example, instead of starting off with 100% of the new diet right away, try adding 10%, 20%, 30%, 40%, etc., until the transition is made. By doing so, you give your cat plenty of time to adjust to the new diet. In addition, you will be able to notice if it causes any problems. Of course, the whole process must be supervised by a vet.

Whenever you see the slightest problem during the transition period, contact him/her to make sure your pet doesn't have any issues or allergies related to the new diet.

What Else Can I Do For A Cat With A Sensitive Stomach?

It may get overwhelming trying to deal with a cat with a highly sensitive stomach. Therefore, it is highly essential to get professional advice during times like these. The following are some of the things you can do while dealing with one:

Provide Proper Hydration

One of the most important aspects is ensuring that your little cat receives enough hydration and water. Ensure that you provide them with fresh water at every interval, especially if your little buddy is on a dry food diet.

Reduce the Treats

If you are someone who loves to spoil their pet with the occasional treats, you should immediately rule it out as the cause of problems. Remember that treats should only comprise ten percent of your cat's diet – anything more than that can prove to be bad for the cat's health.

Try Reducing Their Stress Levels

Although your cat might look happy, you must understand that various environmental factors define his/her eating habits. If your cat has been fighting unusually, it means that they feel stressed and threatened about their territories and boundaries.

Refrain from placing their foods in front of entrances and exits and place them in an area where your little buddy will not be disturbed frequently. This will help them to relax and calm down.

Try to Keep Track of What Your Cat Has Been Eating

When you see your cat devouring something unusual, such as bones, hairballs, or even other types of foreign objects, then you know there is a reason behind it.

Try to identify the items that your cat eats regularly and find ways to prevent them from consuming those particular items.

Make sure that all doors and windows are closed and locked. As much as possible, keep your cat inside whenever you're home. This way, you will be able to control and monitor what goes into their stomach and what may be causing the condition.

Don't Feed Your Cat Leftovers

Whenever you have a meal, try to avoid giving the leftovers to your pet. The cat will enjoy eating the food, but it may be triggering the digestive problem the cat is suffering from.

Cats love eating a plethora of human foods, some of which have been identified as allergens or toxic substances to cats. It would be better just to throw the leftover food away and save yourself the trouble of having to clean up after your cat later.

Mix the Cat Food With Rice

It is known that rice is one of the best foods to help and improve digestion. If you mix cooked rice with the cat food, it can help significantly to stop the vomiting and diarrhea by making the stool harder. Rice is also very easy to digest, which is great for a sensitive stomach. In addition, by preventing diarrhea, rice will also help avoid dehydration.

Frequently Asked Questions

Being a feline parent comes with a ton of responsibilities. It is okay to ask questions and be nervous about what to feed them. Below are some of the most frequently asked questions to help you understand your little buddy's diet better and help their stomach sensitivity.

My Cat Is Coughing Up Hairballs. Is This Related To Their Diet?

The answer is no! It is perfectly normal for a cat to occasionally cough up hairballs as they usually ingest hair through the grooming process; some hair will get stuck on their tongues and end up in their digestive system.

The amount of ingested hair depends on the breed of the cat; a long-haired breed like a Persian is likely to have more hairballs than a short-haired one.

Usually, the hair goes through the digestive system and ends up in the cat's stool or forms a ball that the cat coughs out. However, sometimes, the cat can't regurgitate the hairball and needs to be checked by a vet.

If your cat keeps coughing out the hairballs for too long, then maybe something is wrong with its fur. In this case, there are many things you can do to fix the problem.

You can start by giving your cat a regular brushing to remove as much hair as possible and prevent hairball formation.

You could also use a hairball ointment twice or thrice a week or even opt for an anti-hairball food designed to prevent hairballs and contain more fiber to push the contents of the cat's intestines out.

Can A Cat Suddenly Develop A Food Allergy?

Yes, it is possible for cats to develop food allergies at any time during their lives. Genes play a significant role here, as some cats are genetically predisposed to develop allergies. 

Other factors that could trigger allergies include environmental conditions, stress levels, and dietary changes.

Some common signs of a food allergy include itching around the mouth area, sneezing, runny nose, watery eyes, redness around the ears, scratching, hives, and skin rashes.

Your veterinarian should perform tests to determine if your cat really does suffer from a food allergy.

How Long Does It Take For A Cat To Digest Food?

A cat might take up to 10 to 24 hours to digest food. This is mostly higher than humans, as human beings take around 6 hours to digest food.

The most exciting part of this arrangement is that cats are usually not aware when their next meal will be served, especially if they are not domesticated. Though, on average, a cat takes 20 hours.

Should I Change My Cat’s Diet As He Gets Older?

It is not necessary to change the cat's diet because of age unless the pet needs it. If the cat is in good health and good body shape and eats a balanced diet with necessary nutrients, then there is no need to switch to a different diet.

Senior pet diets are designed to address issues, diseases and deficiencies that the cat may encounter as he/she ages. On the contrary, in this case, changing the diet could be the trigger to many endless health problems.

No need to fix that which is not broken, right?

When Should I Be Concerned About My Cat Vomiting?

In all honesty, it is normal for cats to vomit every now and then. But if it becomes a usual thing, you should look out for other symptoms to decide your next course of action.

If you notice your cat vomiting regularly and sudden changes in their behavior, skin, moods, etc., rush to the nearest vet and consider making a change in their diet immediately.

What’s Better For A Cat With A Sensitive Stomach, Dry Or Wet Food?

Both wet and dry food have their own set of advantages and disadvantages. It solely depends on one's individual preferences. Wet food provides moisture, while dry foods offer nutrients.

Dry foods ensure that your little pet’s dental health gets better, and may be useful in some cases of diarrhea. On the other hand, wet foods help your cat to stay hydrated as it has a higher level of water intake.

Why Are Cats' Stomachs So Sensitive?

The possibilities of why cats could have an upset stomach can be endless. If your little pet is susceptive to sensitivity, even the slightest change in their diet can cause them to get sick. The causes can vary both internally and externally, revolving around the gastrointestinal system.

You need to remember that anything that inflames your cat’s digestive system can be responsible for an upset stomach. If your cat showcases digestion problems after every meal, chances are they are suffering from a sensitive stomach. If it is continuously persistent, then you should definitely consider heading to the vet as soon as possible.


Being a cat parent is not easy – in fact, it is one of the most challenging jobs out there! In case you happen to be a feline parent, you have definitely embarked upon the right place.

Ensuring that your little feline buddy gets all the nutrition they deserve is one of the most crucial parts of being a cat parent.

Besides, there are endless choices available in the market, and chances are you will end up buying the wrong product if you don't do your homework correctly!
