A cat that is having stomach upset can experience many symptoms to name a few:

  • Vomiting
  • Diarrhea
  • Lack of appetite

Good thing we have treatment for the following symptoms

Causes of Cat Vomiting

To start with, cats can vomit due to various reasons that we are going to look at listed below:

  • Overeating

Overeating can be bad for a cat’s health, which is also known as polyphagia.

Regardless, cats love eating and sometimes may overdo it, if it is not regulated. We have observed after a long time if a cat overeat it can lead to vomiting or obesity.

When the food is readily available and is at arm’s reach for the cat, he might eat and eat without control even when full. Besides this, when a household has numerous cats they might compete among themselves during feeding and exceed the required portion to a point of throwing up.

It might seem okay to allow the cat to eat everything and anytime he wants but it can lead to health issues for instance obesity, liver disorder, and diabetes mellitus.

Your cat doesn’t have to vomit due to overeating one can have a feeding schedule plan in the right portions. Particularly, if not sure about what to feed consult your vet for further advice. Also, do not feed kitchen leftovers and give treats when planned for not always.

Apart from this one can buy an automatic feeder that is programmed to feed the cat at various times to prevent overfeeding. Subsequently, put the right food portion in her feeding bowl.

  • Hairball

Even though we have many causes that can cause a cat to vomit like excessive eating or stress most owners think hairball is the leading cause.

Occasionally, you may see the cat trying to groom herself by licking the fur. This is common and the small loose fur that the cat swallows might be problematic after some time. Try to brush your cat regularly to get rid of the loose fur.

When it is in a small portion it might get into the stomach and out with the stool. Even so, sometimes it can form hairballs in the stomach and when unbearable be vomited. It is not a pretty sight as the hairball can be vomited in the house making the house stink.

Not only, are hairball unpleasant but also can cause intestinal blockage. Undoubtedly, hairballs can make the cat cough, gag, and eventually vomit the fur.

Hairballs can occur in both short and long-haired cat breeds although we have remedies for this. Particularly, a hairball diet and gel and ointment can eliminate this cat problem. The ointments are great as enhance the lubrication of the hairballs for them to be passed through the stool. If this doesn’t seem to work after several months one can consult a vet for a proper checkup for another underlying problem.

  • Bowel Irritation

Constipation occurs in cats, dogs, and even human beings. When the bowel movements are not normal and difficult the cat may suffer from constipation, irritation, and vomiting.

Without a doubt, when the cat is straining to get rid of feces it may suffer stomach pain, loss of appetite as she tries to defecate. Although at times the cat may pass small stool or none at all leading to more strain.

Normally the cat would go to the litter box or outside to try to get rid of the feces hoping to be successful. Try not to only feed dry food as this can cause constipation especially if water intake is less. Have a water fountain near the feeding bowl for enough water intake and avoid dehydration. In addition, you can use stool softeners but if this doesn’t get the stool out and vomiting and other symptoms continue go see the vet for further action.

The pain may cause discomfort and agitation for the cat leading to less interaction, defensiveness, and shying away. This can be detected by looking at the cat’s behavior and tail position.

  • Illness

Sometimes the cat may be ill or suffering from a serious disease leading to vomiting. For example, a tumor or blockage in the intestines will require surgery.

To determine what is disturbing the cat and causing the vomiting, various tests can be done before a diagnosis is given.

In the case of a tumor, the vet can schedule surgery to remove it and advise on the feeding program.

For less serious illnesses like bacteria or bowel irritation, the vet may recommend antibiotics or corticosteroids which one can administer to stop the vomiting.

  • Gastroenteritis

Even when the cat’s environment is clean he can still be affected by parasites, worms, viruses, changes in food, and use of medicine.

Cats love playing outdoor in their cat enclosure or running outside in the long grass. This exposes them to parasites and worms which affect the stomach and intestines.

Deworming and a visit to the vet for medication can treat this. Change in diet can also lead to vomiting and hence that is why we recommend changing it gradually. Dietary intolerance to something in food can also lead to vomiting.

Alongside this, the cat can experience abdominal pain and diarrhea too.

Mostly the cat will have episodes of diarrhea during the day and vomit foam, a lot of gagging when drinking.

One may notice some tenderness around the cat’s stomach and he might not want to be touched. Give a lot of water to prevent dehydration due to constant diarrhea.

Unquestionably, this will necessitate a vet examination and blood, urine, feces, and abdominal tests to check for infections and severalty of the situation. After the diagnosis, the vet will prescribe medical treatment and rehydration.

  • Eating Less

Feeding can be complicated even for our feline friends. It is problematic to overfeed and eat fast or to eat less as both can lead to vomiting.

Despite this, if the cat has not eaten for a day he/she may vomit undigested food or bile. When the stomach is empty a lot of acids may be generated irritating the stomach and causing vomiting.

We can treat this by ensuring the cat feeds at the right time and with the right portions. Remember the cat may be eating less due to diet change and maybe a picky eater. Start changing the diet gradually, introduce the new diet in small portions until the cat is used to.

A cat eating less can lead to weight loss or be a sign of illness and may need a vet checkup and diagnosis.


Cats love eating and can consume a lot of food. Despite this, the food should be regulated to avoid vomiting and health issues. When outdoor a cat can eat grass or dead mice which can make him vomit.

Long grass is a hub for parasites and through consuming them the cat can ingest the parasites and suffer from severe abdominal pains.

It can be difficult to diagnose the cause of vomiting in a cat. Nonetheless observe your cat’s behavior, change of diet and eating habits, and consult your vet.

Feed your cat small portions if you notice undigested food in the vomit which could be due to fast eating.

Note the colour and texture of the vomit and take a picture to show the vet when you go for a checkup.

During grooming try to brush your cat daily to remove the loose fur. Lastly, if the vomiting doesn’t stop contact the vet. It might be an underlying problem that needs treatment.
