🐈❤️ SNAP EDUCATIONAL POST: LET’S TALK ABOUT FELINE STOMATITIS!
Stomatitis is one of the most painful, frustrating, and difficult oral conditions a cat can develop. It’s also a condition that many cat owners have never heard of until their own cat is diagnosed.
What is feline stomatitis?
Feline chronic gingivostomatitis (FCGS) is a severe inflammatory condition affecting the tissues inside a cat’s mouth. Unlike ordinary gingivitis, stomatitis can cause extensive inflammation, swelling, and painful ulcerations, sometimes extending into the back of the mouth.
Imagine having painful, raw sores in your mouth every single day. Now imagine trying to eat with that pain. That’s what these cats endure.
What causes it?
The exact cause isn’t fully understood, but stomatitis is believed to involve an exaggerated immune response to substances in the mouth, including dental plaque.
Feline calicivirus is strongly associated with the condition. Other factors, including immune-system abnormalities and certain viral infections, may also play a role.
Signs of stomatitis include:
🐾 Hiding or avoiding mealtimes.
🐾 Approaching food but walking away without eating.
🐾 Drooling, sometimes with blood.
🐾 Extremely bad breath.
🐾 Red, swollen, or bleeding gums.
🐾 Difficulty chewing or dropping food.
🐾 Weight loss and poor grooming.
🐾 Changes in personality, irritability, or hiding.
Now, let’s talk about my Kimmy. ❤️
If you read my rescue story earlier today, you met Kimmy, one of the two little sisters I trapped at an abandoned house in Red Bluff many years ago.
Kimmy has battled stomatitis for many years.
The very first sign that something was wrong wasn’t drooling, bleeding, or even bad breath.
She started hiding at mealtimes.
That was my first clue. A cat that normally looks forward to eating suddenly avoiding food is telling you something.
My personal cats are raw fed, but that diet isn’t ideal for Kimmy with her painful mouth. So she gets her own special meals.
I water down pâté-style canned food and mix in kitten milk replacer for some added fat and calories. This makes her meals easier to lap up without having to chew. The goal is to keep her eating comfortably and maintain her weight.
Over the years, steroid injections have been helpful in controlling Kimmy’s inflammation and discomfort. However, steroids come with risks, particularly with repeated or long-term use. They can increase the risk of diabetes, suppress the immune system, and contribute to other complications.
They are not a cure.
What about removing the teeth?
For many cats with severe stomatitis, extracting most or all of their teeth can dramatically improve their quality of life.
This is called a full-mouth extraction (FME).
It sounds extreme, but many cats do remarkably well without teeth. Removing the teeth eliminates much of the plaque-retaining surface that contributes to the inflammatory response.
However, not every cat responds to extractions, and some continue to struggle with inflammation even after every tooth has been removed.
Personally, I have been reluctant to go the full-mouth extraction route with Kimmy if at all possible. It is a very invasive procedure, and removing every tooth is not something I take lightly.
Kimmy’s teeth are nice and clean, and I have concerns that putting her through such an extensive procedure may not provide the relief we’re hoping for.
That doesn’t mean clean teeth rule out stomatitis or that extractions wouldn’t help. Even cats with beautiful-looking teeth can benefit from FME because the problem involves the immune system’s response to plaque, not simply visible dental disease.
It’s a difficult decision, and one that should be made with a veterinarian experienced in feline dentistry, weighing the severity of the disease, the cat’s overall health, and the likelihood of improvement.
For now, my preference has been to manage Kimmy’s condition as conservatively as possible while keeping her comfort and quality of life the priority.
Stomatitis is not a one-size-fits-all disease.
What about feral cats?
This condition is especially heartbreaking in feral and community cats.
Imagine being a feral cat with a mouth so painful you can barely eat. Nobody can easily examine your mouth, administer daily medications, or monitor your weight.
These cats can slowly deteriorate while food is sitting right in front of them.
For some, extensive dental extractions can be life-changing. Others may require additional medical management, and severe cases can be extremely challenging.
The important lesson here is PAY ATTENTION TO CHANGES IN EATING HABITS!
Cats are incredibly good at hiding pain.
A cat that suddenly becomes a picky eater may not be picky at all.
A cat that hides at feeding time may be hungry but afraid of the pain associated with eating.
And a cat with clean-looking teeth can still have significant oral inflammation.
Kimmy is a perfect example of why knowing your cat’s normal behavior is so important.
She’s been dealing with this condition for years, and managing it has required adjustments, patience, and close attention to her comfort.
❤️ Stomatitis is not just a dental problem. It’s a serious, painful inflammatory disease that can drastically affect a cat’s quality of life.
Our cats depend on us to recognize when something isn’t right. Sometimes the smallest change in behavior is the biggest warning sign.
No cat should have to suffer silently with a painful mouth.
