Do Maine Coons Have Sensitive Stomachs?

Do Maine Coons have sensitive stomachs? Yes, some do experience stomach sensitivity to varying degrees, and establishing the underlying cause can be a challenge. Though a cat’s stomach is known for its strong constitution, the balance can be upset by a variety of factors.

Maine Coons are one of the healthiest purebred cats. Screening and good breeding practices are gradually eliminating their known genetic health problems.

However, there is one condition that can’t be bred out because it is generally related to diet or environment, and that’s stomach sensitivity that leads to vomiting or diarrhea.

Maine Coons, as a breed, do not have overly sensitive stomachs but like any cat, they can have occasional stomach disorders. Eating too quickly is a well-known cause of vomiting in Maine Coons and occasionally a change of food introduces short-term diarrhea.

Why some Maine Coons have more sensitive stomachs than others

Maine Coon diarrhea and vomiting result when something irritates the cat’s stomach lining.

It’s not really clear why some Maine Coons have more sensitive stomachs than others.

However, it’s a fact that some Maine Coons have more balanced diets than others and this plays a large role in a cat’s digestive health.

You should endeavor to provide a Maine Coon with a diet that’s suitable for each life stage. It’s easier to do this by buying pre-prepared food from a recommended, trusted brand.

Do Maine Coons Have Sensitive Stomachs

Occasionally a Maine Coon will just be predisposed to suffer from stomach sensitivity and all you can do is work with your vet to establish the cause and learn how to control it the best you can.

Should your Maine Coon get sick occasionally, don’t stress. All cats have occasional stomach disorders that are nothing to worry about.

Are Maine Coons prone to diarrhea?

Though isolated bouts of diarrhea can be attributed to such things as bacteria, viruses, or intestinal worms, regular Maine Coon diarrhea often occurs as a result of something in its diet causing stomach sensitivity.

If your Maine Coon suffers from diarrhea on a daily basis, try changing its food. A diet high in meat protein and low in grains is ideal.

If adjusting what it eats doesn’t stop your cat’s diarrhea, you should seek advice from a vet.

Purina Pro Plan Fortiflora is a very popular probiotic supplement that can help relieve Maine Coon diarrhea. It’s conveniently available on Amazon. You can see more details and the current price by clicking here.

Maine Coon diarrhea: the common causes

Many factors can lead to Maine Coon diarrhea. Here are the most common:

  • Eating too fast
  • Food intolerance
  • Dietary indiscretion
  • Bacteria in their food
  • Intestinal parasites

You’ll find more information about each of these and how to remedy them further down.

Signs of a sensitive stomach in Maine Coons

There are several indicators that your Maine Coons is suffering from a sensitive stomach, temporary or otherwise.

Here are seven signs of a sensitive stomach in Maine coons:

  • Vomiting
  • Loss of appetite
  • Flatulence
  • Diarrhea
  • Constipation
  • Lethargy
  • Hunched body position

It is not unusual for a Maine Coon to have the occasional stomach disorder. It happens with all creatures from time to time and is perfectly normal.

Most of the time, symptoms disappear after a day and your cat will resume its normal routines.

If sensitivity symptoms persist, it’s time to consult your vet to establish the reason, especially if your cat has stopped drinking.

Why do Maine Coons sometimes develop sensitive stomachs?

While it’s easy to spot if a cat has a stomach disorder, it’s not so easy to determine the cause.

Isolated sensitive stomach episodes in Maine Coons

Here are common causes of isolated stomach problems in Maine Coons:

1. Eating too fast


Eating too fast is a habit of some Maine Coons and causes more of a problem if the food is dry. Dry food absorbs fluid in a cat’s digestive system and expands.

If your cat has gobbled down a lot of dry food too quickly its stomach becomes overfull and up comes the food!

Cure – Encourage slower eating

If your cat regularly eats too quickly and regurgitates its dry food, swap to wet food as this is less likely to cause this type of vomiting.

If you have this problem with wet or dry food there are several things you can try:

  • Raised and tilted food bowls can really help as they keep a cat’s mouth at a higher level which helps to reduce vomiting. I found a perfect example on Amazon. See more details and the current price by clicking here.
  • Use a large flat plate and spread your cat’s food out as widely as possible
  • Put a clean golf ball in the dish (nothing smaller!) so your cat has to move it around to get at the food
  • Use a puzzle feeder
  • Buy a bowl with a raised hump in the center – this somehow slows down eating

2. Dietary indiscretion


Dietary indiscretion is often a problem with outdoor cats who might be tempted to eat anything they find.

With indoor or outdoor cats, human leftovers that should have been disposed of are sometimes irresistible.

Cure – Prevent access to leftover food

Apart from keeping them inside, there’s not a lot you can do to stop cats scavenging outside.

Indoors, however, you can ensure your cat doesn’t eat anything other than its own food by disposing of your leftovers and keeping all other food out of reach.

3. Frequently changing food brands


You may think your cat will appreciate trying a wide variety of food but the truth is, this often leads to stomach sensitivity.

Cure – stick to a brand that works!

Don’t change your cat’s food too often. This doesn’t mean you can’t swap brands but just do it carefully, looking out for any consequences.

4. Stale food


If your cat doesn’t eat its wet food straight away, after several hours it becomes a breeding ground for bacteria, especially in hot weather. If a cat then decides to finish the food, it may disagree with them

Cure – Regularly pick up stale food

You don’t have to throw food away the moment your cat wanders away but do consider after a few hours on a warm day how fresh it is.

If a crust has formed on the surface, consign it to the garbage can!

5. Bacteria


Bacteria might be ingested through contaminated food or water. Even a new pouch of food can be contaminated, though this is rare.

Puddle drinkers might sup up bacteria. However your cat comes in to contact with bacteria, it can cause digestive problems.

Cure – be vigilant

It’s difficult to stop a cat lapping up water outside but you can minimize these water sources by not leaving any vessels around to collect rainwater.

Cat food doesn’t have a particularly attractive aroma to us but you should be able to tell if it smells bad as you open it.

Withhold food for 12 to 24 hours to let your cat’s stomach settle. In some cases, bacterial infections may require antibiotics to be administered.

6. Viruses


There are many different strains of viruses that can cause severe digestive problems in cats. Some are highly contagious, for example, Feline Enteritis.

Cure – rehydrate, withhold food, and medicate

There is no cure for a virus, it just has to run its course. There are several steps you can take to help a cat feel better during its recovery:

  • Give plenty of hydration on a drip at the vets if necessary
  • Offer only bland food that’s easy to digest
  • Administer any medication your vet provides to stop the vomiting and diarrhea

7. Intestinal Parasites


Intestinal parasites can cause vomiting and diarrhea. They are typically contracted if your cat catches mice, rats, or other infected prey.

In multicat households, Giardia is a parasite that can be caught from the feces of other cats that share the same litter tray. It causes chronic diarrhea.

Cure – Administer parasite medication

Your vet might prescribe regular parasite treatments to keep intestinal worms at bay. It’s a good idea to make sure you give these to your cats regularly.

Fenbendazole and metronidazole are two drugs commonly used to kill Giardia. These will be prescribed by a vet after a positive diagnosis.

All household cats will need treatment and all litter boxes should be thoroughly cleaned and disinfected.

8. Food intolerance


Occasionally a cat can have an intolerance to certain food ingredients, especially in foods not intended for their consumption.

Cure – Avoid trigger foods

If a particular brand of food seems to trigger a reaction in your cat, avoid it.

Be careful about giving your cat scraps from your plate as there are many human foods that Maine Coon cats should not eat. These include but or not limited to:

  • Dairy products
  • Chocolate
  • Raw egg
  • Grapes and raisins
  • Liver
  • Onion
  • Garlic
  • Tuna

9. Medication


Some cat medications can cause side effects such as stomach sensitivity.

Cure – Check medication

If you suspect a medication your cat is taking is making its stomach sensitive, read the side effects on the packet.

Speak to your vet to see if there is an alternative or something to help reduce your cat’s reaction.

If the side effects are outweighing the benefits of the medication, ask your vet if you can take your cat off it

10. Furballs


As they lick their fur, Maine Coons ingest a certain amount of fur. This can form balls in their stomach. A cat will often regurgitate these before they pass into their intestines.

If a large furball enters a cat’s intestines, it may not pass right through to the bowels. This can cause a blockage and all sorts of digestive issues.

Cure – Regularly groom out loose fur

The best thing you can do to lower your cat’s risk of developing furballs is to groom it as much as possible to remove loose fur.

This is to your benefit too as you won’t have to clean up the resulting vomit.

11. Swallowing an inedible item


Few cats are known to eat non-edibles but occasionally, it does happen – and sometimes by accident.

If your cat swallows something it shouldn’t it can play havoc with its digestive systems, especially if it causes a blockage.

Cure – Keep small things out of reach

Don’t play with your cat with any toy that it could easily swallow by accident. If your cat chews anything that can easily be swallowed, put it out of its reach.

It’s far better to avoid your cat swallowing something it shouldn’t than to end up with it needing emergency surgery to remove an intestinal blockage.

Do Maine Coons Have Sensitive Stomachs

Recurring sensitive stomach episodes in Maine Coons

What can cause a recurring sensitive stomach in a Maine Coon? Here are 5 causes:

1. Food allergies


Foods cats can have allergies to include beef, fish, chicken, and dairy products. Most of the time, these cause itchy skin conditions but occasionally produce gastrointestinal symptoms too.


If your cat is continually reacting with stomach issues to certain foods simply avoid that food.

However, if you strongly believe it is allergic to all the main protein groups as described above, your vet can help to determine this.

2. Feline Inflammatory Bowel Disease (IBD)


Feline Inflammatory bowel disease (IBD) is a chronic irritation of a cat’s stomach or intestines.

There are many causes of inflammatory bowel disease and often it is hard to determine one in particular. Some known causes are:

  • Bacterial infection e.g. Salmonella or E. coli
  • Parasitic infection such as worms, Giardia or Tritrichomonas
  • Allergy or intolerance to a specific component in their diet


Ideally, IBD is treated by diagnosing what’s causing the cat’s reaction. If a cause cannot be determined, the disease is referred to as idiopathic (disease is present, but there is no identifiable cause).

Many cases of IBD are classed as idiopathic.

Treatments include deworming, dietary changes, supplements, and medication.

3. Stomach and intestinal cancer


Lethargy, decreased appetite, vomiting, and diarrhea can be signs of gastrointestinal lymphoma. 


Chemotherapy may be offered but this is dependent on the stage and size of the cancer. The drug, prednisone, may be administered.

4. Metabolic disease


Metabolic disease in cats covers conditions such as hyperthyroidism, kidney failure, and liver failure. Symptoms can include increased sensitivity of the stomach.

Symptoms of hyperthyroidism include increased appetite, weight loss and sometimes vomiting and diarrhea.

Maine Coons are predisposed to the genetically transmitted Polycystic Kidney Disease (PKD). It isn’t a treatable condition.

Cats are capable of masking liver failure completely. You may notice the odd bout of vomiting and it is very easy to assume this is just a little stomach disorder.


A vet will correctly diagnose a metabolic disease and recommend the most effective treatment in each case.

Hyperthyroidism is treated with a thyroid hormone supplement.

Though there is no cure for PKD or Kidney failure, treatment can prolong life.

Liver failure requires fast intervention and hospitalization. The success of any treatment depends on how far progressed the condition is.

Are Maine Coons lactose intolerant?

Many people believe Maine Coons are allergic to dairy whereas, the truth is they are lactose intolerant – as are all cats.

Kittens are able to digest their mother’s milk but as soon as they are weaned, the enzyme lactase that breaks down lactose is no longer produced.

If an adult Maine coon drinks milk, it cannot digest it properly resulting in undigested milk fermenting in its stomachs causing cramps, vomiting, and diarrhea.

Resist the temptation to treat your Maine Coon to milk. Maine Coons should only drink water! Avoid milk or your cat will suffer from the digestive issues it creates.

If you don’t think your cat drinks enough water milk is not an option.

However, cats get much of the fluid they require from good quality wet food, which is why wet food should be offered daily as opposed to an all dry food diet.

How to prevent Maine Coon digestive issues

It is difficult to prevent all Maine Coon stomach sensitivity but there are some good practices to follow.

  • Make sure your Maine Coon always has access to clean water to keep it well hydrated
  • Recognize which foods do not irritate your Maine Coon’s digestive system and stick with them
  • Be vigilant for anything that gives your Maine Coons a digestive problem and remove the cause immediately

Best Cat Food for Sensitive Stomachs, Vomiting, and Diarrhea

If your cat has regular bouts of mild stomach disorders, choosing the right diet is key to reducing its symptoms.
