How to Handle a Cat Vomiting White Foam

Causes of Vomiting White Foam in Cats

There might be a number of underlying reasons, including indigestion, hairballs, gastritis, irritable bowel syndrome, and more, if your cat is vomiting white foam. Your veterinarian can assist you in determining the cause of your cat's illness and how to make your pet feel better. The reasons of some of these issues and how your cat may be affected are explained below.


Similar to humans, cats also create hydrochloric acid and other gastric secretions in their stomachs to help in food digestion. The accumulation of liquid and acid, though, might irritate the stomach and cause your cat to vomit if they skip a meal or aren't fed on time. In addition to white foam, cats with indigestion may also vomit yellow foam. If you and your veterinarian believe that your cat's vomiting is caused by indigestion, your veterinarian may advise providing short, frequent meals at the same time each day to prevent any accumulation of stomach acid.


All cats lick themselves to groom themselves, which eventually results in their eating fur. Fur can occasionally pass through their stools, but it can also accumulate and become difficult to pass. Your cat will vomit up the fur when this happens because it needs to go somewhere. If your cat is throwing up white foam without any fur yet, it may be the beginning of a hairball. There are over-the-counter nutritional supplements available in chewable or gel form to prevent hairballs. Adopting a regular brushing routine will also assist in removing any excess fur that your cat could eat when grooming itself.


It's likely that your cat has upset their stomach with anything they've eaten if they tend to get into things they shouldn't. When this occurs, in addition to seeing vomiting blood and/or bile, you could also witness vomiting white foam. Additionally, your cat can be displaying a decline in appetite, a downcast demeanor, lethargy, or dehydration. If your cat is throwing up due to gastritis, your veterinarian will know just what to do.

Irritable Bowel Syndrome (IBS)

One of the most typical causes of vomiting in cats is irritable bowel syndrome, often known as inflammatory bowel illness. IBS-afflicted cats may potentially develop chronic decompensation or diarrhea. If your veterinarian has a suspicion that your cat has IBS, they will want to order lab tests to confirm the diagnosis before coming up with a treatment plan to help your cat feel better.


Pancreatitis may affect cats just like it can affect dogs and people. Either acute or chronic disease can exist. Additionally, it may co-occur with conditions including diabetes, liver illness, or gastrointestinal or liver problems. Lethargy, lack of appetite, dehydration, weight loss, low body temperature, jaundice, fever, and gastrointestinal discomfort may also be indicators of in cats. Your veterinarian will probably start treating your cat's with fluid therapy and drugs if that is the cause of the vomiting.

Hepatic Insufficiency

Both milder symptoms like vomiting, anorexia, or weight loss in cats as well as more severe ones like jaundice, or a yellowing of the skin and sclera, are signs of liver illness (whites of the eyes). Although liver disease cannot be cured, the symptoms can be controlled. To help your cat feel better, your veterinarian will develop a treatment plan.


Similar to dogs and people, increased thirst and urination, as well as weight loss and dehydration, are the main signs of diabetes in cats. Make an appointment right once to have your cat examined by your veterinarian if they are increasing unexpectedly, either alone or in conjunction with any of the other symptoms listed. Your veterinarian may recommend starting insulin therapy or a straightforward diet adjustment, depending on the severity of your cat's diabetes.

Renal Insufficiency

Senior cats commonly develop chronic kidney disease (CKD). Other signs of CKD include a marked rise in alcohol use, a change in urine output, appetite loss, dehydration, a dreary mood, a thin coat, and weakness. Kidney disease cannot be treated, like liver illness, but the symptoms can be controlled. Ask your vet to examine your elderly cat if it begins to exhibit any urinary symptoms. If they determine that your cat has CKD, they can discuss supportive therapy with you, including both at-home and hospital care, to assist your cat manage his or her renal insufficiency.


Another extremely typical condition affecting geriatric cats is an overworked thyroid. In addition to vomiting, symptoms may include diarrhea, increased urination, and loud vocalizations. Weight loss may also occur despite increased eating and drinking. Your doctor will order bloodwork to examine the thyroid hormone levels if your elderly cat exhibits any of these signs. Your veterinarian will discuss daily medication with you if your cat does truly have hyperthyroidism in order to address the disease's symptoms.


When vomiting and diarrhea are present in a young kitten that hasn't received routine deworming, this may indicate an untreated parasite illness. This may be swiftly fixed by examining a stool sample and prescribing the proper dewormer.

Don't succumb to the fallacy that it's normal for cats to vomit occasionally if you're dealing with a pukey cat at home. Your cat (and flooring) will thank you if you make an appointment with your veterinarian to help determine the cause of your cat's vomiting.

If you suspect your pet is sick, call your vet immediately. For health-related questions, always consult your veterinarian, as they have examined your pet, know the pet's health history, and can make the best recommendations for your pet.
