You’re probably familiar with some of the most common afflictions in house cats. Hairballs, food sensitivities, and the occasional battle wound from fighting with another cat are all things you’d be able to identify on your own. But what on earth is a rodent ulcer?
- Rich in real animal protein
- Blend of omega-3
- Natural sources of taurine
- High in protein
When you hear the phrase “rodent ulcer” you might understandably think it’s some horrible disease contracted by contact with rodents. In actuality, however, the disease has nothing to do with rodents. Rather, it is an allergic reaction caused by any number of things that results in painful lesions forming on the cat’s lips, chin, and inside the mouth. Though it is not the most common condition seen in cats, it is bad enough that you should at least familiarize yourself with it so you can identify it quickly and seek treatment for your cat at the first sign of symptoms.
In this article, we’ll explore the subject of rodent ulcers in depth to learn what they are, what symptoms they produce, and how to treat them. You’ll also learn about the role diet plays in rodent ulcer treatment and see our top picks for the best food for cat with rodent ulcers.

What Are Rodent Ulcers in Cats?
The name “rodent ulcer” is very misleading because this condition has nothing to do with contact with rodents. It can, however, be triggered with other organisms like fleas. Technically, rodent ulcers are signs of a condition called feline eosinophilic granuloma complex. This term refers to three different types of skin lesions in cats: eosinophilic plaque, eosinophilic granuloma, and indolent ulcers.
The exact cause of eosinophilic granuloma complex in cats is unknown, but some studies suggest that it is a hypersensitivity reaction (essentially an allergic reaction) to certain triggers. For cases that are recurrent or chronic, an allergic reaction is the more likely the cause. Some studies suggest, however, that the underlying cause may be at least partially inheritable or genetic.
Here are some of the potential causes of eosinophilic granuloma complex:
- Allergies to fleas
- Chemicals in plastic or rubber bowls
- Food sensitivity or allergy
- Exposure to environmental pollutants
- Synthetic ingredients in cat litter
- Compromised immune system (such as FIV)
Eosinophilic granuloma lesions often form inside the cat’s mouth, so you may not notice them immediately. Unfortunately, this condition can be very severe, and damage caused by the lesions may be permanent if the condition isn’t treated quickly. This is why it is important to at least familiarize yourself with the disease and its symptoms so you can get your cat treated as quickly as possible.
When it comes to diagnosing a rodent ulcer, cat symptoms include:
- Lesions forming inside the cat’s upper lip
- Swelling of the lip and around the ulcerated area
- Lesions forming on the body, most commonly the belly
- Demarcated, flat areas of swelling and redness
- Hair loss from the ulcerated area
- Severe itching around the ulcerated area
- Ulcers forming on the hind legs and foot pads
Now that you have a better understanding of this health problem, you may be wondering which is the best option for rodent ulcer treatment. In the next section, we’ll talk about treatment options and explore how changing your cat’s diet might help.
How Can Changing Your Cat’s Diet Help?
The first step in diagnosing eosinophilic granuloma or rodent ulcer is to rule out other causes for the ulcers. Your veterinarian will want to make sure that your cat’s problems aren’t being caused by a fungal, bacterial, or viral infection. Some of the diagnostic tests your veterinarian may perform during diagnosis may include:
- Internal organ function tests
- Skin scrape for mites
- Complete blood count (CBC)
- Skin impression test
- FeLV and FIV test (should be negative)
- Fungal culture test
If all of these tests are negative, your veterinarian will move on to discussing potential treatment options for rodent ulcers. The most common treatments for eosinophilic granuloma are steroids or antibiotics, maybe both. Though bacteria may not be directly involved in causing rodent ulcers, secondary bacterial infections are very common and should be treated as well.
If you’re wondering about at-home treatment for rodent ulcer, however, there may be some options for you to consider. First and foremost, you’ll want to identify the trigger that caused your cat to develop a negative reaction. Once you’ve identified it, all you need to do is prevent your dog from coming into contact with it in the future and then take steps to heal his ulcers and restore proper health. If your cat’s issues are caused by a food allergy or sensitivity, changing your cat’s diet could help with treatment.
So, what role does diet play in restoring your cat’s health?
Changing your cat’s diet can help him recover from rodent ulcers and boost his immune system to prevent a recurrence – it can also give your cat the strength and energy he needs to heal the ulcers themselves. In cases where your cat’s rodent ulcers are not seasonal and you suspect a food allergy as the trigger, performing a food trial to identify and then avoid the food allergen is a necessary step.
What to Look for in a Good Cat Food for Rodent Ulcers
When it comes to shopping for the best food for rodent ulcers, quality is key. The higher the quality of the food, the more digestible it will be which means that your cat gets more of the essential nutrients he needs to recover. If you’re not sure exactly what is causing your cat’s allergy, you should still switch to a limited ingredient diet (LID) for at least 8 weeks until your cat’s symptoms resolve. At that point you can continue feeding the limited ingredient food or try to identify the ingredient your cat is allergic to so you can switch to a more affordable food free from the problem ingredient.
Here are some of the things we look for in a good cat food for rodent ulcers:
- High-quality, natural ingredients. Low-quality ingredients like fillers and by-products are likely to trigger food allergies or make existing sensitivities worse. Choose a cat food that contains wholesome, natural ingredients and no by-products.
- Free from common food allergens. The most common food allergens for cats are chicken, beef, fish, and dairy products. Grains are not the most common allergen, so you should only worry about a grain-free diet if your cat has been diagnosed with a grain allergy.
- Limited number of ingredients. The fewer ingredients in your cat’s food, the fewer things he could potentially react to. Look for a recipe with a novel animal protein as the first ingredient with a short list of other main ingredients (aside from supplements)
- Anti-inflammatory ingredients. Rodent ulcers are an inflammatory condition marked by redness and swelling around the ulcerated areas. To help your cat recover, find a cat food rich in anti-inflammatory ingredients like omega-3 and omega-6 fatty acids.
- Antioxidants for immune system support. In addition to reducing inflammation, omega-3 fatty acids can help boost your cat’s immunity. Antioxidants are also good for the immune system and may help your cat heal.
Now that you have a better understanding of what rodent ulcers are, what causes them, and how changing your cat’s diet might be able to help, you’re ready to see our recommendations for the best food! But first, read on to see how we make our recommendations.
How Do We Make Our Recommendations?
All of the cat foods we recommend are evaluated in accordance with AAFCO food nutrient profiles which outline the minimum nutritional needs of cats in various life stages (kitten or adult). In order to determine whether a cat food meets these requirements, just look for an AAFCO statement of nutritional adequacy on the package. It will be on the label and will look something like this: [X Product] is formulated to meet the nutritional levels established by the AAFCO Cat Food Nutrient Profiles for all life stages. After establishing that the product is complete and balanced, we go on to a more in-depth analysis of the ingredients.
Here are some of the requirements for a cat food to receive our recommendation:
- A source of high-quality animal protein as the first ingredient
- At least 30% crude protein for kittens and at least 26% for adults
- A minimum of 9% crude fat for kittens and adults
- A balance of omega-3 and omega-6 fatty acids, primarily from animal sources
- A rich blend of nutrients from natural sources and supplements, as needed
- Limited carbohydrate content from digestible sources (like whole grains and veggies)
- No low-quality fillers, by-products, or artificial additives (preservatives, dyes, or flavors)
Before getting into our top picks for the best rodent ulcer cat food, we want to make it clear that changing your cat’s diet is NOT a substitute for veterinary care. You need to take your cat to the vet to determine the underlying cause of his lesions and to find the proper treatment. If your veterinarian confirms that food allergies are the issue, at that point changing your cat’s diet could help resolve the symptoms and prevent them from returning.

Frequently Asked Questions
- What are the most common rodent ulcer cat symptoms? – The most common and most visible rodent ulcer cat symptoms are, of course, the lesions themselves. They can form on the lips or inside the inner lip as well as other parts of the body such as the belly, the hind legs, and the foot pads. Accompanying the lesions themselves may be areas of swelling, redness, itching, and hair loss. The severity of these symptoms increases the longer you wait to treat it.
- Will cat rodent ulcer go away on its own? – If you do absolutely nothing to treat your cat’s rodent ulcers, they will not go away on their own. In fact, the longer you wait to seek treatment the worse they will get – you’ll also be increasing your cat’s risk for secondary infection which can become very severe. As soon as you suspect that your cat is suffering from eosinophilic granuloma, you need to see your vet. Left untreated, the damage caused by the ulcers could become permanent.
- What is the best natural remedy for rodent ulcers? – If you’re wondering how to treat rodent ulcers in cats at home, changing your cat’s diet can remove the trigger for what started the problem, but your cat will also likely need steroids and/or antibiotics to truly resolve the issue. Natural remedies can support your cat’s recovery by reducing inflammation and supporting his immune system, but dietary changes should not be a replacement for veterinary care – they should only be used as a supportive therapy.
- What is the best food for cat with rodent ulcers? – The answer to this question differs depending on the cat. Assuming that your cat’s rodent ulcers are caused by a food allergy or sensitivity, the best food to treat rodent ulcers will be one that is free from the ingredient your cat is reacting to. To perform a food trial on your cat and to give his body time to heal, we recommend a limited ingredient diet with a novel source of protein. The recipe should also be rich in anti-inflammatory ingredients and antioxidants to support your cat’s immune system.
- What else do I need to know about rodent ulcers? – Though the name may sound silly, the condition itself is actually quite serious. The longer you leave these lesions untreated, the more severe they will become and the more likely it is that your cat will sustain permanent skin damage. This condition also comes with a high risk for secondary infection which, left untreated, could become systemic and might start affecting your cat’s internal organ function. Do not take symptoms of this condition lightly – it is always better to err on the side of caution when it comes to your cat’s health, so talk to your veterinarian about your concerns!
Though you may have never heard of rodent ulcers in cats or eosinophilic granuloma, you shouldn’t just dismiss symptoms as unimportant. This condition has the potential to cause permanent damage to your cat’s skin, not to mention the pain and discomfort of the lesions themselves.
After talking to your veterinarian about your cat’s health and determining the proper course of treatment, we recommend switching to one of the recipes we’ve reviewed above. It may not heal your cat completely, but it may remove the trigger that is causing your cat’s condition to worsen and may help support his immune system for a speedier recovery.
