Dealing with a cat that has a sensitive stomach


When cats show signs of a sensitive stomach, pet parents can easily become complacent. Perhaps we get used to seeing cats cough up hairballs every couple of weeks, leading us to believe stomach irritation is just part of being a cat. But cat puke, when it doesn’t have any signs of a hairball, can be a symptom of something more serious.

When a cat has an upset stomach, it comes with four tell-tale signs - 

  • Vomiting
  • Diarrhoea
  • Licking lips (which often accompanies nausea)
  • Refusing food
Let’s take a look at the common causes of stomach upsets in cats & when to know if your cat’s stomach issues are serious, and what you can do to soothe your cat’s stomach.

What causes stomach upset in cats?

Most cats get a tummy ache from time to time, and these are the most common causes of stomach sensitivity.


If your car suffers from separation anxiety, or if you recently moved or added a family member to your home (human or animal), that stress could be the source of your cat’s stomach issues. If your cat is up to it, carve out some extra one-on-one time to alleviate their emotional distress.


Is your cat being treated for fleas or some other medical issue? Check the dosage and application. When cats ingest too many topical medications through grooming, it can irritate the stomach.

Eating something toxic (like the leaf of a plant, an insect or something that kitty wanted to paw at and bite) can also cause issues. Beware: Some plants can be fatal, so make sure you rid your house and garden of poisonous plants.

Diet and diet changes

If your cat has an allergy or sensitivity to an ingredient — corn, soy and other filler ingredients in bargain brands are common — that can lead to stomach upset.

When is a cat’s sensitive stomach serious?

A cat with a sensitive stomach can indicate underlying medical issues. For that reason, make sure your cat is getting their annual checkups — twice a year for kittens and senior cats. A thorough examination complete with bloodwork can rule out a serious health problem and give you peace of mind that you’re doing the right thing for your cat.

Vomiting can be a symptom of many medical issues in felines. Here’s a partial list:

  • Intestinal parasites
  • Pancreatitis
  • Virus bacteria
  • Cancer
  • Abdominal obstruction (blockage produced by a large hairball or ingested string)
  • hyperthyroidism
  • Kidney failure
  • Liver failure

If your feline friend is vomiting several times a day and has refused food for 48 hours, your cat should be seen immediately by a professional. Other signs that something is seriously wrong include lethargy, weight loss and sudden changes in behaviour, like hiding.

If your cat is regularly producing non-watery vomit that’s free of grass and hairballs, even if it’s only monthly, make that vet appointment so the kitty can start getting treatments and relief.

One of the first things your vet may want to rule out is intestinal worms, which are pretty common in cats that spend time outdoors. The culprit could be roundworms or hookworms, but tapeworms are most common.

Tapeworms occur when a flea larva eats the eggs of a tapeworm. When a kitty accidentally ingests the larvae through grooming or biting an itchy flea bite, the tapeworm eggs get released during the digestive process. From there the eggs hatch and the tapeworms attach to your cat’s intestinal lining. Indoor cats are less likely to suffer tapeworms, but it happens, as fleas can find their way into the home. If your vet finds evidence of tapeworms or other parasitic problems, they’ll recommend a dewormer for cats, followed by regular prevention treatments.

Keeping your cats tummy worry-free

Once you and the vet rule out serious issues, stay focused on promoting good digestive health in cats.

Regular deworming treatments

Depending on your cat and their outdoor habits, many animal health care professionals recommend preventive treatments every one to three months.

Regular wellness visits

An annual examination for your cat establishes a baseline for their health, and regular bloodwork can help cat health professionals identify problems early before they cascade into something more serious.

Groom your cat regularly

Daily brushings can minimize the volume of hair that ends up in your cat’s stomach. In addition, paying close attention to your cat each day will make it easier for you to notice changes that could be early signs your cat needs medical attention.

Feed your cat a high-quality diet

To soothe your cat's sensitive tummy, look for diets that are made from high-quality ingredients with meat or meat meal listed first on the ingredients. Cheap fillers like corn should be avoided, as these can be the irritating root cause of your cat’s stomach issues. Also use wet food as the moist content of wet food is a great addition to your cat’s diet due to its hydrating qualities that helps them absorb more nutrients.

Trying a grain-free diet can give your cat’s tummy a break. Opus Lynx is the perfect example of a grain-free solution for cats. Opus Lynx or Senior Lynx (for senior cats) aids in better digestion, better absorption of nutrients, and enhances your cat’s ability to fight off infection. If you want to see less vomiting, fewer hairballs and fewer messes in the litterbox, you’ll want to pick up a bag today.
