Why is My Cat Throwing Up White Foam? (Explained!)

Your cat throwing up white foam is usually nothing to worry about and is often caused by hairballs. If your cat is healthy and doesn’t have any other symptoms, then you can try some home remedies to help them with the hairballs.

However, if your cat is vomiting more than usual or has other symptoms, then you should take them to the vet to get checked out.

Why Is Cat Throwing Up White Foam?

If your cat is throwing up white foam, it could be a sign of an underlying health condition. While not always serious, vomiting can indicate that something is wrong and should be checked out by a vet. Some possible causes of vomiting white foam in cats include:


If your cat is throwing up white foam and also happens to be grooming excessively, it’s likely they’ve swallowed too much fur which is now causing them to vomit.

Hairballs are usually not harmful and can be treated at home with special grooming products or a high-fiber diet.


Vomiting can sometimes be a symptom of an infection, such as gastroenteritis. If your cat is also showing other signs of being unwell, like lethargy or lack of appetite, then it’s best to take them to the vet for a check-up.

Dietary issues

If your cat has suddenly started vomiting after switching to a new food or eating something different, it could be that their stomach doesn’t agree with the change. Stick to feeding them their usual diet and see if the vomiting stops.

Vomiting white foam in cats isn’t always cause for concern, but if it persists or is accompanied by other symptoms.

What Does It Mean When a Cat Throws Up Foam?

When a cat throws up foam, it usually indicates that they are suffering from an intolerance or allergy to something in their diet.

It could be something as simple as a change in the type of food they are eating or a new ingredient in their food.

If your cat is throwing up foam frequently, you should take them to the vet to rule out any underlying health conditions.

What Does It Mean If Your Cat is Throwing Up White?

If your cat is throwing up white, it generally means that they are bringing up undigested food.

This could be because they are eating too fast, or it could be a sign of a more serious issue such as an intestinal blockage.

Home Remedy for Cat Vomiting White Foam

If your cat is vomiting white foam, it’s likely due to an upset stomach. There are a few things you can do at home to help settle your cat’s stomach and stop the vomiting.

First, offer your cat small amounts of water or milk to drink. Avoid giving them too much at once as this can make vomiting worse.

You can also try offering them ice chips or bland, low-fat food like boiled chicken or plain rice. If your cat continues to vomit or seems in pain, contact your veterinarian for further advice.

In most cases, home treatment will settle your cat’s stomach and stop the vomiting.
