A cat’s swollen lip is a common ailment for cats. Cats are susceptible to abscesses and infections that can result in this symptom. A cat’s mouth area is not as sensitive as a human’s, so the swelling may be more noticeable around the sides of the mouth or on top of their nose.

Swollen lips may also happen due to trauma from an injury or being hit by something hard such as a ball. That is something to check first.

What are the most common causes of a swollen lip?

Allergies

Although it is not the most common cause of swelling, there is a chance that your cat’s lip could be experiencing pain and inflammation due to allergies. In some instances, animals can experience allergies just like humans can, causing a painful allergic reaction and your cat’s swollen lip.

Food and environmental allergies are typically the culprits when a cat develops swelling of its lip. A veterinarian can help you figure out what could be causing your pet’s reaction to reduce discomfort and keep it safe. Other issues are food and water hygiene – are you using plastic food bowls that may be scratched and harbour bacteria. Or it may just be a plastic allergy to a plastic bowl.

Dental issues

If your cat seems to be avoiding eating or having trouble eating, a fat lip could mean there is an issue with its teeth. A dental abscess, broken teeth, an infected pocket in the gums or tooth rot usually accounts for it and can lead to swelling that pushes the lip out resulting in temporary deformation of your cat’s lips, whether top lip or lower lip.

Your veterinarian may prescribe medication – a course of antibiotics – to deal with the infection, or there may be a small surgery involved to remove the infected tissue or tooth and relieve the symptoms.

Feline acne

Feline acne or chin acne acne is another term for infected hair follicles of your cat’s chin. Much depends on where the infection is – is if is close to the mouth, then you might think at first pass that this is a swelling in the lips. lower lip or upper lip.

There are many causes for chin acne on cats, from allergies to ingrown hairs. Your veterinarian can treat chin acne and identify what the cause is – which may be more common in young cats than others. It is unlikely to cover the entire head and will improve with a topical treatment on your cat’s skin.

Eosinophilic granuloma complex

Although the cause behind eosinophilic granuloma complex is unclear, cats with swollen lips may show granulomas or small areas of inflammation. In some cases, it’s possible to recognize a lump in the skin around your cat’s mouth.

Eosinophilic granuloma complex generally requires a short treatment of anti-inflammatory drugs to reduce swelling and help soothe the skin. Your vet can assess the area and see if there are any other topical manifestations of the condition which is not an allergic reaction.

Cancer and tumors

Though not extremely likely, there is a slight chance your cat has developed a tumor on its upper or lower lip that is causing the swelling. A veterinarian can determine if it’s a benign growth or cancerous tumour by an examination of the top lip and bottom lip.

Various treatments are available, including surgeries. Your vet can estimate the level of life quality going forward. This problem is most common in elderly felines, although there is no difference if it is a male cat or a female cat.

Other causes

Sometimes the cause of your cat’s swollen lips is straightforward and requires no further treatments. If it’s mosquito season, your cat may simply have a bite, and the cat’s swollen parts will go down in a few days.

Your cat may have also sustained a minor injury or scratch that’s causing swelling to, say, it’s bottom lip. Always worth a check

You can help by watching

Watch the swelling for a few hours to a day to see if there are changes. If your cat will allow you, inspect the swelling site to see if you can see a bump, bruise, bite, or even an attached insect like a tick. Clean the area thoroughly if you can to help avoid further infections.

If it goes down on its own, check in a few weeks anyway for the sake of well being of your cat and to check if your cat is showing any other signs or might in fact need treatment. But remember for the sake of your cat that no condition should be left untreated.

Conclusion

Cats are social

Cats are known for their ability to lick themselves clean. This behavior, combined with the fact that cats groom each other and fight among themselves by biting one another’s faces, means it is not surprising that a cat may occasionally have swollen lips.

Keep a close eye

The most common causes of swelling in these areas include bacterial infections or allergic reactions to food items such as fish or chicken bones. For this reason, cat owners should watch closely for signs of an infection like pus discharge from the mouth area or feverishness accompanied by lethargy and weight loss.

Is it just an allergy?

In cases where allergies are suspected, vets might prescribe antihistamines or a steroid injection to help relieve symptoms; otherwise your veterinarian will recommend surgery if you can’t identify any underlying cause after conducting tests on the animal blood samples.

Or something more serious?

If your cat has swollen lips, it’s important to recognize that this could be a sign of an underlying health problem. The good news is there are some easy ways to care for them at home or take them to see the vet if needed.
