🐛 Cheyletiellosis (“Walking Dandruff”) in Cats – 2025 Vet Guide 🐱
Hello vigilant cat caregivers! 😺 I’m Dr Duncan Houston BVSc, here with a comprehensive 2025 guide to cheyletiellosis—a contagious mite infestation often called “walking dandruff.” We’ll explore mites’ life cycle, signs, diagnosis, treatment options, prevention, and when to contact Ask A Vet. Let’s keep your cat—and home—clean, comfortable, and healthy! 🧼✨
1️⃣ What Is Cheyletiellosis?
Cheyletiellosis is caused by Cheyletiella mites—tiny parasites that live on skin and feed on debris. Named “walking dandruff,” these mites cause crusting, inflammation, and intense itchiness in cats and can affect dogs, rabbits, and even humans!
2️⃣ Mite Life Cycle & Transmission 🔄
- 🔬 Adult mites live in fur and lay eggs on hair shafts.
- 🪶 Eggs hatch on skin surface in 3–10 days.
- 🐛 All life stages (egg → nymph → adult) happen on the cat—no need for a host switch.
- ✨ Mites move easily between animals via direct contact or contaminated bedding.
3️⃣ Who Is at Risk?
- 🐾 Outdoor cats or those in multi-pet households.
- Immunocompromised or young kittens with fragile skin.
- Recently adopted cats without vet exams.
- Households with exposure to other affected pets.
4️⃣ Recognizing the Signs 👁️
- ❗ Visible white flakes moving in coat—“walking dandruff.”
- 🧴 Greasy, scaly patches, especially on back, neck, tail base, head.
- 😿 Itching, hair loss, red irritated skin.
- 🐾 Secondary infections like crusting or bacterial infection.
- 👨👩👧👦 Humans may develop mild rash in contact—transient.
5️⃣ Diagnosing Cheyletiellosis 🔍
Diagnosis is usually confirmed by:
- 🧹 Visual flea combing—mites and eggs cling to the comb.
- 📄 Adhesive tape test pressed onto skin, examined under microscope.
- 🔬 Skin scrapings if deeper infections suspected.
- 🧾 Thorough history—contact with affected animals, sudden outbreak in multiple pets.
6️⃣ Treatment Approaches 💊🛁
✅ Topical & Spot-on Treatments
- 🧴 Selamectin or imidacloprid-moxidectin monthly—kills mites and eggs.
- 🧹 Lime sulfur dips weekly for 4–6 weeks—very effective though smelly!
⚕️ Systemic Medications
- 💊 Ivermectin oral or injection—used off-label under vet monitoring.
- 💊 Fluralaner (Bravecto) oral or topical for 12‑week protection.
- 💊 Spinosad (Comfortis) oral monthly—effective alternative.
🛁 Treating Secondary Issues
- 💧 Medicated shampoos to soothe skin.
- 💊 Antibiotics if bacterial infection present.
- 🐾 Anti‑inflammatories or antihistamines for itch relief.
🏠 Environmental Cleaning
- 🧼 Wash bedding, blankets, toys in hot water weekly.
- 🧽 Vacuum floors and furniture; dispose vacuum bag immediately.
- 🛋️ Isolate infected pets until treatment is complete to prevent spread.
7️⃣ Recovery & Prevention 🌟
- 🗓️ Treatment runs for at least 4–6 weeks to break mites’ life cycle.
- 🔁 Follow‑up combing or tape tests around week 6 to confirm elimination.
- 🧼 Continued cleaning and treatment for all pets in household.
- 🚫 Prevent re‑infestation by keeping pets on regular parasite prevention.
8️⃣ Human Health Perspective 🧑⚕️
Cheyletiella mites can bite humans, causing mild, itchy rash. It doesn’t persist long if pets are treated—but you may need to treat itching with topical creams and avoid further contact until pets are cleared.
9️⃣ When to Contact Ask A Vet 📲

- 🐛 Visible mites, stubborn scratching, or crusting despite home care.
- 👶 Multi‑pet household—others showing signs too.
- 🍃 Persistent rash on a person with close pet contact.
