Cat Swollen Lip: Causes, Symptoms And Treatment

Many times our cats contract something that causes a swollen lip. There are many health problems that can lead to swollen lips in cats. A swollen lip is not a good thing, but it doesn’t have to be the end of your cat’s life either. We will discuss several conditions that may cause Cat Swollen Lip.

Why is my cat’s lip swollen?


Allergies are a common problem in cats, but they can be hard to diagnose since there are so many different types of allergies and because cats don’t always show their symptoms the same way that humans do. If you suspect your cat has an allergy, talk to your vet about testing for it. They can run tests to see if your cat has food or environmental allergies or even skin allergies if you think something else is going on with him.

If your vet finds that your cat has an allergy, they may prescribe medications like antihistamines to help reduce swelling and itching. They’ll also recommend changing his diet, so he doesn’t eat the things that cause his symptoms to flare up as much. And, most importantly, they’ll let you know how often you should bathe him!

Dental conditions

Dental disease is a common problem among cats, putting them at risk of causing swollen lids or lips. The teeth and gums of your cat’s mouth are incredibly important for maintaining healthy teeth and gums; if they’re not working properly, you’ll see the symptoms of swollen cat lip when the gum tissue gets infected.

If you notice your cat’s lips getting bigger than usual, or if you notice your cat licking their lips excessively, you should take them to the vet for evaluation. They may need to have their teeth cleaned or removed if they’re causing swelling in other areas of the body via inflammation caused by infection from dental problems.

Cancer and tumors

Tumors are abnormal growths on the body that cause pain, swelling, and loss of appetite and weight. Tumors can be found in places such as the mouth and tongue, throat, and skin. Cats with a tumor will usually develop a swollen lip or face due to swelling in this area. Cat swollen lip is not always caused by cancerous cells; it could also be caused by other medical conditions such as inflammation or dehydration.

Cats with cancer often experience symptoms such as weight loss and coughing up blood. In some cases, cats will develop a swollen lip due to swelling in this area, making it difficult for them to eat or drink water properly, causing more breathing problems and leading to more complications overall!

Physical injury

There are several reasons why your cat could have swollen lips. One of the most common causes is physical trauma, such as fighting with another animal. The injury may be minor or severe, depending on how hard the cat was hit and what other injuries were sustained at the time. Other causes include poisoning and hematomas (bleeding from ruptured blood vessels).

The swelling will usually go away within a few weeks, but if it persists for longer than that, you should take your cat to the vet for an examination. You can also try using a cold compress or ice pack on the affected area to reduce swelling and discomfort.


Cat swollen lip is a condition that occurs when the soft tissue of the mouth and lips is swollen. The swelling can be either mild or severe, and it can happen anywhere from the lower to the upper lip.

It may be accompanied by other symptoms, including:

  • Red gums.
  • Scabs or sores around the mouth.
  • Mass of any kind.
  • Bleeding or oozing.
  • Bad smell in their mouth.
  • Drooling.
  • Decreased eating or drinking.

treatment for cat swollen lip

The good news is that a cat’s swollen lip is usually a very simple condition. It is caused by an infection or a foreign object in your cat’s mouth, and the treatment can be done at home.

To treat your cat’s swollen lip, you must first ensure it’s not an allergic reaction to something he ate. If you suspect this, take him to the vet so they can check for food allergies and other causes of swelling.

If it isn’t food-related, then you can use over-the-counter treatments. One option is to put petroleum jelly on the swollen area and leave it there overnight—it should be absorbed into the skin during sleep and help soothe the inflammation. You can also apply ice packs directly on the affected area, but be careful not to freeze your cat! If using ice packs, wrap them in a towel first, so they don’t damage or injure your pet’s skin.

Another option is to take over-the-counter medications such as aspirin or ibuprofen (don’t give these without consulting with your vet first!). They may help relieve pain and reduce swelling by reducing inflammation within


When should I take my cat to the vet for a swollen lip?

If your cat’s lip is swollen, and it doesn’t seem to be getting better with time, you should take them to the vet.


The most common causes for a swollen lip are dental issues and other abnormalities. If there are reasons to think the swelling is severe—for example, it doesn’t go away on its own within a couple of days—you should take your cat to the vet so they can identify the problem and treat it accordingly.
