What are cat warts, and why does my cat have a lot of them? Cat warts are small, benign skin growths caused by a virus. When a cat has many warts, it’s often due to a widespread infection of the virus or a weakened immune system.
Cats can develop warts for a variety of reasons, and it’s helpful for pet owners to grasp the common causes and characteristics of these skin growths. This article delves into why your cat might have a lot of warts, exploring the underlying viral culprits, how they spread, and what you can do if your feline friend is affected by these common cat skin conditions. We’ll also touch upon cat wart removal and feline warts treatment.

Fathoming the Cause: The Role of Viruses
The primary reason cats get warts is exposure to specific viruses. These viral invaders cause the cells in a cat’s skin to grow abnormally, leading to the formation of these rough, bumpy growths.
The Culprit: Feline Papillomavirus
The most common agent responsible for warts in cats is the feline papillomavirus. This virus, like its human counterpart, targets the skin cells. There are different strains of the feline papillomavirus, and each can cause slightly different types of warts in different locations on the cat’s body.
- How it infects: The virus typically enters the cat’s body through minor cuts, abrasions, or even through mucous membranes in the mouth. Once inside, it infiltrates the skin cells and triggers rapid cell division.
- Appearance of warts: These viral warts on cats can vary in size, shape, and color. They often appear as small, raised bumps, sometimes with a cauliflower-like texture. They can be skin-colored, grey, or black.
Other Potential Causes of Cat Skin Lesions
While viruses are the main offenders, other factors can contribute to or mimic warts:
- Bacterial infections: Certain bacterial skin infections can cause raised bumps that might be mistaken for warts.
- Fungal infections: Some fungal infections can also manifest as skin lesions.
- Allergies: Skin allergies can lead to itching and scratching, which can result in secondary infections and inflammatory bumps.
- Parasites: Mites or other external parasites can cause skin irritation and small bumps.
- Neoplasia (Tumors): In some cases, what appears to be a wart could be a benign or, more rarely, malignant skin tumor. This is why veterinary diagnosis is crucial.
Interpreting the Spread: How Warts Appear
A cat doesn’t suddenly sprout dozens of warts without a reason. The appearance of multiple warts usually indicates an active infection and, often, a compromised immune system.
Transmission of the Virus
The feline papillomavirus is contagious, although not highly so compared to some other viruses.
- Direct Contact: The virus is shed from existing warts. Cats can get infected by direct contact with a wart on another infected cat.
- Contaminated Surfaces: Less commonly, a cat might contract the virus by touching surfaces that have come into contact with infected skin cells, such as grooming tools, bedding, or toys. This is more likely if the cat has a small cut or abrasion.
- Vectors: Insects like mosquitoes can potentially spread the virus, though this is considered a less significant mode of transmission.
Why More Warts? Factors Influencing Infection
If your cat has a lot of warts, several factors might be at play:
- Weakened Immune System: This is a primary reason why a cat might develop numerous warts. A robust immune system can fight off the virus and prevent it from spreading. Cats with compromised immune systems, due to age, illness (like FIV or FeLV), or certain medications, are more susceptible to widespread infections.
- Initial Widespread Exposure: A cat might have been exposed to a high viral load, perhaps through prolonged contact with an heavily infected animal or a highly contaminated environment.
-
Location of Warts: Warts can appear anywhere on a cat’s body, but they are often seen in areas where skin is thinner or more exposed to trauma.
- Oral Warts on Cats: This is a common presentation. Warts can appear inside the mouth, on the tongue, gums, lips, or around the nose. These can sometimes interfere with eating or cause discomfort.
- Foot Warts: Warts on the paws or between the toes can make walking painful and lead to limping.
- Head and Neck: Warts are frequently found on the face, ears, and neck.
- Body: While less common, warts can also appear on the trunk and limbs.
Deciphering the Signs: What to Look For
Recognizing warts early can help with timely intervention.
Visual Characteristics
- Appearance: Small, raised bumps, often rough or cauliflower-like. They can be flesh-colored, white, grey, black, or even pink.
- Location: As mentioned, they can appear anywhere, but common sites include the mouth, lips, nose, ears, face, paws, and legs.
- Number: A few scattered warts can occur, but a large number of warts, or warts that are rapidly increasing, are a cause for concern.
Associated Symptoms
In most cases, warts are not painful or itchy. However, some cats may exhibit:
- Licking or Chewing: If warts are irritating or in an accessible location, a cat might lick or chew at them. This can lead to secondary infections or further irritation.
- Discomfort: Warts on the paws or in the mouth can cause discomfort, leading to changes in eating habits or gait.
- Bleeding: Warts can sometimes bleed if they are irritated, scratched, or traumatized.
When to Seek Veterinary Care
While many cat warts are benign, it’s always best to consult a veterinarian if you notice any new skin growths on your cat, especially if:
- They appear suddenly and in large numbers.
- They change in size, shape, or color.
- They bleed or cause your cat discomfort.
- They interfere with eating or movement.
- You are unsure if the growth is indeed a wart.
A veterinarian can correctly diagnose the growth and rule out other, more serious conditions.
Comprehending the Diagnosis Process
Your vet will perform a physical examination to assess the warts.
Diagnostic Tools
- Visual Inspection: The veterinarian will examine the warts, noting their size, location, and appearance.
- Biopsy: If there is any doubt about the nature of the growth, or if it appears suspicious, the vet may recommend a biopsy. A small sample of the wart is taken and sent to a laboratory for microscopic examination. This can definitively determine if it is a wart, a different type of lesion, or a tumor.
- Blood Tests: In some cases, blood tests might be recommended to assess your cat’s overall health and immune status, especially if there’s a suspicion of underlying illnesses affecting the immune system.
Feline Warts Treatment: Options and Approaches
Once diagnosed, your veterinarian will discuss the best course of action for cat wart removal and feline warts treatment. Often, if warts are not causing problems, observation may be the recommended approach.
Natural Resolution
Many cases of papillomatosis in cats (the medical term for warts caused by papillomavirus) will resolve on their own. The cat’s immune system can eventually recognize and fight off the virus, causing the warts to shrink and disappear over time. This can take several months to a year or more.
Medical Interventions
When warts are bothersome, spreading rapidly, or causing health issues, treatment may be necessary.
-
Surgical Removal:
- Excision: Small warts can be surgically removed under local anesthesia or sedation. The excised tissue is often sent for histopathology to confirm the diagnosis.
- Cryotherapy: Freezing the warts with liquid nitrogen is another option, similar to how warts are treated in humans. This can cause the wart tissue to die and fall off.
- Electrocautery: Using heat to destroy the wart tissue is also an effective method.
-
Topical Treatments:
- Medicated Wipes or Ointments: Your vet may prescribe topical treatments containing salicylic acid or other compounds designed to help break down wart tissue. These require consistent application.
- Immune Stimulants: In some cases, topical or injectable immune-stimulating medications may be used to help the cat’s body fight the virus more effectively.
-
Oral Medications:
- Antivirals: While not commonly used for simple warts, specific antiviral medications might be considered in severe or persistent cases.
- Immune Modulators: Medications that boost the immune system can sometimes be prescribed.
-
Alternative Therapies:
- Homeopathic Treatments: Some owners explore homeopathic remedies or supplements to support the immune system. While anecdotal evidence exists, scientific backing for their efficacy in treating cat warts is limited. Always discuss these with your vet before administering them.
Prevention Strategies
While it’s difficult to completely prevent viral infections, certain measures can help reduce the risk.
- Hygiene: Maintain a clean environment for your cat, especially if there are other pets in the household.
- Minimize Exposure: Keep your cat indoors to reduce exposure to other animals and potential environmental contaminants.
- Boost Immune Health: Provide a high-quality diet, ensure regular veterinary check-ups, and manage any underlying health conditions that could weaken the immune system.
Common Cat Skin Conditions: A Broader Perspective
It’s important to remember that warts are just one of many common cat skin conditions. If you notice skin changes on your cat, it’s always wise to consult your veterinarian. Other conditions that might present with bumps or lesions include:
- Fleas and Flea Allergy Dermatitis: Small, red bumps, often around the neck and base of the tail, accompanied by itching.
- Mites (e.g., Mange): Can cause crusting, hair loss, and itchy bumps.
- Fungal Infections (Ringworm): Circular patches of hair loss with red, scaly skin.
- Bacterial Infections (Pyoderma): Pustules, scabs, and redness.
- Eosinophilic Granuloma Complex: Inflammatory skin lesions, often appearing as raised red bumps or plaques.
- Skin Tumors: Benign or malignant growths that require veterinary diagnosis.
