🦠 Papillomatosis in Cats: Comprehensive Vet Guide – 2025 🐱

Hello attentive cat guardians! 😺 I’m Dr Duncan Houston BVSc, here with a detailed 2025 guide on papillomatosis—a rare viral condition that causes warty growths in cats. We’ll explore types, signs, diagnosis, treatment, prevention, and when Ask A Vet can assist. Let’s ensure your cat’s skin and mouth stay healthy and wart-free! ✨

1️⃣ What Is Papillomatosis?

Papillomatosis is caused by feline papillomaviruses (FcaPVs), leading to benign skin or oral warts. Most common forms include:

• 🦷 Oral papillomas: warts on lips, tongue, palate.
• 🐾 Skin papillomas: small warty growths on ear tips, eyelids, nose, footpads.

These growths are generally benign but may ulcerate, become infected, or rarely transform into cancers.

2️⃣ How Does It Happen?

• 🦠 Infection by FcaPV types (e.g., FcaPV-2 for skin, FcaPV-3, -4 for oral lesions).
• Transmission through direct contact or environmental exposure—warts shed viral particles.
• Young or immunocompromised cats are more susceptible.

3️⃣ Who Can Get It?

• 🍼 Kittens or young cats exposed to virus early.
• 😿 Immunocompromised adults—e.g. FeLV/FIV infected, or on steroids.
• 📅 Outdoor cats or those in multi-cat households.
• 🦠 Rare in healthy, indoor-only cats.

4️⃣ Recognizing Symptoms 👀

• 🦷 Oral papillomas: small, soft, cauliflower-like growths on mouth tissues—may cause drooling, bad breath, trouble eating.
• 🐾 Skin papillomas: raised, wart-like lesions on external surfaces—usually painless but may bleed or itch if irritated.
• 🔄 Growths often slow-growing and may appear in groups.
• ⚠️ In severe cases, ulceration, secondary infection, or obstruction of the oral cavity may occur.

5️⃣ How Vets Diagnose It 🔎

Diagnosis involves:

• 🩺 Physical and oral exam to identify wart-like lesions.
• 🔬 Biopsy or fine needle aspirate for histopathology—confirms papillomavirus and rules out cancer.
• 📷 Sample analysis via PCR may detect viral DNA.
• 🦠 Culture and analysis to rule out other skin lesions like basal cell tumors.

6️⃣ Treatment Approaches 💊

🛑 Active Monitoring

• Some papillomas regress spontaneously over weeks to months.
• Monitor for changes like growth, ulceration, or bleeding.

✂️ Surgical Removal

• Recommended for large, ulcerated, infected, or obstructive oral papillomas.
• Performed under anesthesia; biopsy submitted for confirmation.

💊 Medical Therapies

• Topical antivirals (e.g. imiquimod) may help skin papillomas.
• Surgical adjuncts: carbon dioxide laser ablation, cryotherapy for skin lesions.
• Immune modulation with interferons or cimetidine in selected cases.
• Antibiotics if secondary bacterial infection is present.

🦷 Oral Care & Pain Control

• Pain medication and appetite support for oral lesions.
• Soft, palatable foods if eating is disrupted.
• Regular oral hygiene and monitoring.

7️⃣ Recovery & Follow-Up 🌟

• Warts often regress within 6–12 weeks after removal or treatment.
• Regular rechecks (every 2–4 weeks) to ensure healing or regression.
• Biopsy‑confirmed lesions lower recurrence risk.
• Immunosuppressed cats may need ongoing monitoring.

8️⃣ Complications & Prognosis 🩺

• Generally good prognosis for benign papillomas.
• Oral lesions can affect eating—nutritional support is key.
• Rare malignant transformation—especially in immunocompromised or FeLV-positive cats.
• Secondary bacterial infection should be treated promptly.

9️⃣ Prevention & Owner Guidelines 🛡️

• Isolation during outbreaks—avoid contact between affected pets.
• Maintain overall immune health—balanced diet, vaccinations, stress management.
• Prompt removal and biopsy of unusual skin/oral growths.
• Regular dental check-ups and cleanings.
