Mouth Ulcer Symptoms in Cats: What You Need to Know

Signs You Shouldn’t Ignore

Mouth ulcers in cats are not uncommon, but they can be easy to miss. These sores can be caused by a variety of underlying conditions, ranging from dental disease to viral infections. The symptoms often manifest subtly at first, but they can escalate quickly if left untreated.

Refusal to eat: The most telling sign of a mouth ulcer in your cat is a sudden disinterest in food. You may notice your cat licking her lips or pawing at her mouth. Eating becomes uncomfortable, and as the pain increases, your cat might refuse to eat altogether, leading to weight loss and general lethargy.

Drooling: Cats are naturally clean animals, so if you spot unusual drooling, it’s often a sign of discomfort. This could indicate a mouth ulcer or another oral issue causing pain.

Bad breath: While bad breath isn’t unusual in older cats, persistent foul odor from your cat’s mouth may signal an infection, particularly in combination with ulcers.

Red or inflamed gums: Cats with mouth ulcers often have inflamed gums. The area around the ulcers may look swollen, red, or even bleed.

Pawing at the mouth: Your cat may try to alleviate the discomfort by pawing at her face. This could indicate the presence of a painful ulcer inside her mouth.

What Causes Mouth Ulcers in Cats?

Feline Calicivirus (FCV): This virus is a leading cause of upper respiratory infections in cats and can result in the formation of ulcers in the mouth. Cats with FCV often exhibit additional symptoms such as sneezing, nasal discharge, and eye irritation.

Dental disease: Periodontal disease, tartar buildup, or tooth infections can lead to ulcers, particularly if the gums are already irritated. Untreated dental issues may worsen over time, exacerbating the risk of ulcers.

Trauma: Sometimes, cats can accidentally injure themselves, whether from chewing on sharp objects or rough play, which may cause ulcers to form.

Autoimmune conditions: Certain autoimmune diseases, like feline pemphigus or eosinophilic granuloma complex, can cause ulcers as the body attacks its own tissues.

Diagnosing Mouth Ulcers in Cats

If your cat displays any of the symptoms mentioned above, a trip to the veterinarian is crucial. Veterinarians typically examine the cat’s mouth and may recommend blood tests, X-rays, or a biopsy to determine the cause of the ulcers.

Oral examination: During a routine examination, your vet will check for ulcers, swelling, and inflammation in your cat’s mouth. They will also assess the cat's overall dental health to rule out any periodontal disease.

Blood tests: Bloodwork may be required to screen for infections such as Feline Leukemia Virus (FeLV) or Feline Immunodeficiency Virus (FIV), both of which can increase the likelihood of ulcers.

X-rays: If dental disease is suspected, the vet may take X-rays to assess the condition of your cat’s teeth and jaw, ensuring no abscesses or fractures are present.

How Are Mouth Ulcers Treated?

Antibiotics: If an infection is present, antibiotics are often prescribed to help clear the infection and prevent it from spreading.

Antiviral medications: If the ulcers are caused by feline calicivirus, your vet may prescribe antiviral medications to help manage the symptoms, although there is no cure for the virus itself.

Pain relief: Managing your cat’s pain is a priority. Non-steroidal anti-inflammatory drugs (NSAIDs) or opioids may be administered, depending on the severity of the pain.

Dietary changes: Softening your cat’s food or switching to a liquid diet may help ease the pain while the ulcers heal. High-quality nutrition is key to supporting recovery.

Dental care: If dental disease is the root cause, professional cleaning or tooth extraction may be necessary. Your vet will clean your cat’s teeth, remove tartar buildup, and address any infections.

Topical treatments: In some cases, oral gels or rinses may be used to treat ulcers directly. These treatments reduce inflammation and promote healing.

Prevention and Long-term Care

Preventing mouth ulcers in cats is possible, but it often involves a combination of regular vet visits, proper dental care, and managing any underlying health conditions.

Routine dental check-ups: Regular veterinary visits for oral health examinations and cleanings can help prevent the buildup of plaque and tartar, which often leads to periodontal disease and, ultimately, ulcers.

Vaccinations: Ensure that your cat is up-to-date on vaccinations, particularly those that protect against feline calicivirus and other common respiratory infections.

Monitor for early signs: Always keep an eye on your cat’s eating habits, and be vigilant about any signs of discomfort, drooling, or bad breath. Early detection is key to preventing more severe health issues.
