Why Is My Cat Foaming At The Mouth?

If your cat is foaming at the Mouth, it could be a sign of numerous medical conditions. There are many causes for cats to foam at the Mouth, but most can be treated with proper veterinary care.

What is Foaming at the Mouth?

Foaming at the Mouth is a symptom of a serious medical condition in cats. While it can be caused by many different things, including an anatomical abnormality or allergies to food or environmental toxins, it is usually caused by an infection or inflammation of the salivary glands.

This condition can lead to oral ulceration, even loss of teeth, and tooth decay in the back teeth. If you notice your cat foaming at the Mouth, it’s important to take them to the vet immediately so that they can receive treatment for this condition.

Why Is My Cat Foaming At The Mouth?

Fear and Anxiety

Fear and anxiety are common causes of foaming at the Mouth.

If your cat is experiencing these symptoms, it may be an indication that they are in pain. The cat’s Mouth is an important part of their digestive system, and when they experience pain, they may try to mask it with foam.

Fear can also lead to self-trauma, which causes cats to feel more anxious. This anxiety can cause them to try to escape the situation or reduce pain by vomiting.

Dental Disease

The most common causes of dental disease are tartar, plaque, and gingivitis. These are all conditions that your cat’s Mouth develops over time as they age. If your cat has any of these conditions, there is a chance that they’ll experience foam at the Mouth. Your vet may be able to help with treating any underlying causes of your cat’s dental issues and prevent future episodes from occurring again.

Toxic Ingestion

Toxic Ingestion is a common cause. It can be caused by things as simple as a piece of food left on the floor, or it can be caused by something that has been in your cat’s stomach for a while.

If your cat has eaten something that is toxic to them (like rat poison), you will notice that they are foaming at the Mouth and vomiting. If you see this happening frequently, it could be an indication that your cat may have eaten something toxic.

Viral Infections

A viral infection can cause a cat to foam at the Mouth. Viruses can cause any number of symptoms in cats and dogs, including vomiting, diarrhea, and coughing. In addition to these symptoms, some viruses can cause congestion in your cat’s throat and nasal passages that can cause them to cough or sneeze repeatedly.

If you notice your cat foaming at the Mouth, it’s important to remember that an infection does not always cause it; viral infections are more common than bacterial infections. If you think your cat may have a viral infection, contact your veterinarian immediately for treatment.


The most likely cause of this condition is a plant allergy. If your cat has allergies, the plant pollen can trigger an allergic reaction in the cat’s body that causes mouth-foaming. Fleas or ticks may also be to blame for this condition.

What to do when a cat is foaming at the Mouth

If you notice that your pet has started to foam at the Mouth, check for signs of an alteration in their diet. If you find that food allergies are involved, you should eliminate any suspect foods from their diet and consult with your veterinarian about other possible causes for the problem.

If you suspect an underlying medical condition might be causing this reaction, it’s important to take your cat to also see a veterinarian as soon as possible.

Prevention of Foaming at the Mouth

Foaming at the Mouth in cats is a common problem that can be prevented with a few simple steps. Here are some tips to help prevent foaming at the Mouth in your cat:

  1. Give your cat plenty of water. Cats are known for their thirst, so keeping them hydrated is important.
  2. Make sure your cat has been vaccinated for feline distemper and rabies. These diseases can cause vomiting, diarrhea and even seizures.
  3. Give your cat a teaspoon of honey every day. Honey will help thicken the lining of your cat’s stomach so it can better hold back vomit or diarrhea if they start experiencing symptoms.

Cost of Foaming at the Mouth

The cost of treating Foaming at the Mouth for a cat can vary depending on what type of treatment is being considered. The most common treatments include:

  • Antibiotics, which will treat the bacteria that cause the foaming
  • Antifungal medications, which will treat fungus
  • Steroids, which will help to reduce inflammation and swelling in the Mouth
  • Pain medication, which may be necessary if there is a lot of pain

The cost of treating Foaming at the Mouth for a cat may range from $100-$300 per dose, depending on how severe it is or how long it lasts.


Your cat may be foaming at the Mouth and this could be a symptom of a more serious illness. However, if this is indeed the case, it’s important to know what you should look out for and how to tell if your kitten needs immediate vet care. In other words, if your cat is foaming at the Mouth, don’t stress while you wait for help.
