Mange in Cats: Causes, Symptoms, Diagnosis, and Treatment
Identify mite infestations early to prevent complications and protect your cat’s skin.
Mange is a skin disease in cats caused by several types of parasitic mites, resulting in intense itching, hair loss, and skin lesions. Though less common in cats than in dogs, mange can be highly uncomfortable and, in some cases, contagious and even dangerous. Understanding how to spot, treat, and prevent mange is critical for every cat owner concerned about their petâs health and wellbeing.
What Is Mange?
Mange is a collective term for skin diseases caused by microscopic mites that live on or burrow into a catâs skin. Different species of mites cause distinct forms of mange, each with its own symptoms and modes of transmission. The most notable types include:
- Notoedric Mange (Feline Scabies) â Highly contagious, caused by Notoedres cati.
- Demodectic Mange â Caused by Demodex cati and Demodex gatoi; not all forms are contagious.
- Otodectic Mange (Ear Mites) â Caused by Otodectes cynotis, primarily affecting the ears.
- Cheyletiellosis â Known as âwalking dandruff,â caused by Cheyletiella mites.
Core Symptoms of Mange in Cats
Mange mites provoke significant irritation and discomfort when crawling on, feeding from, or burrowing into your catâs skin. While many other skin conditions may produce similar signs, the following symptoms can suggest mange:
- Intense Itching (Pruritus)
- Hair Loss (localized or generalized)
- Skin Lesions, Welts, or Bumps, including:
- Rashes
- Sores or oozing patches
- Miliary dermatitisâclusters of small, crusty bumps
- Eosinophilic granuloma complexâred, raised, and often oozy skin
- Crusty skin, often around the head and neck (noted in notoedric mange)
- Skin flakes that may appear to move (âwalking dandruffâ from Cheyletiella mites)
- Excessive Grooming or Hair Pulling, particularly on the abdomen (Demodex gatoi)
- Chin Acne or Lesions, mainly from Demodex cati
- Ear Problems: Head shaking, ear scratching, ear droop, buildup of dark brown wax (Otodectes cynotis)
It is important to note that these signs are not exclusive to mange. Allergies, bacterial and fungal skin infections (like ringworm), and flea infestations can all mimic mange symptoms, necessitating professional diagnosis.
Types of Mange in Cats: A Detailed Overview
| Type | Mite Species | Area Affected | Contagious? | Key Symptoms |
|---|---|---|---|---|
| Notoedric Mange | Notoedres cati | Head, neck, ears (can spread body-wide) | Yes | Severe itching, crusts, alopecia, red sores |
| Demodectic Mange | Demodex cati, Demodex gatoi | Hair follicles, skin (abdomen, chin) | Some forms | Itching, hair loss, chin acne, hair pulling |
| Otodectic Mange | Otodectes cynotis | Ear canals, can spread outward | Yes | Ear scratching, wax, possible ear infection |
| Cheyletiellosis | Cheyletiella spp. | Skin surface (especially back) | Yes | Skin flakes (âwalking dandruffâ), mild itching |
What Causes Mange in Cats?
The central cause of mange is infestation by parasitic mites. Most mites are acquired when a cat comes into direct contact with another infected animal. Other transmission methods include:
- Indirect Contact â Mites can survive for a time in the environment (bedding, grooming tools, furniture) and be picked up by other animals.
- Compromised Immune System â Some mites, such as Demodex cati, normally live on feline skin in small numbers. They only cause mange if the catâs immunity drops due to illness, age, medications, or stress, allowing overgrowth.
- Exposure to Stray or Outdoor Animals â Unsanitary group living conditions facilitate rapid spread, especially with notoedric and sarcoptic mites.
- Introduction of Infected Cats â Ear mites and cheyletiellosis are commonly introduced to indoor cats via new feline additions.

How Is Mange Diagnosed?
Because mange symptoms mimic several other feline skin disorders, a veterinarianâs diagnosis is crucial. The vet typically performs:
- Physical Exam â Inspecting skin, fur, ears, and affected areas for visible signs, patterns, and severity.
- Skin Scrapings â Collecting and viewing skin/fur samples under a microscope to detect mites or eggs.
- Ear Swab â For otodectic mange, examining earwax or debris for live mites.
- Medical History & Environment â Gathering information about exposure, dietary changes, stress, immune status, or contact with new pets.
- Other Tests â To rule out allergies, bacterial/fungal infections, or ringworm.
Complications and Risks of Untreated Mange
Left untreated, many forms of mange can worsen and cause serious complications, such as:
- Spread to Other Pets or Humans (noted for scabies and Cheyletiella mites)
- Secondary Infections â Scratching and open sores allow bacteria, leading to deeper infections.
- Full-Body Infestation â Some forms can spread from localized patches to general body-wide irritation.
- Life-Threatening Illness â In advanced cases, susceptible cats (young, elderly, immunocompromised) may become critically ill.
Treatment Options for Mange in Cats
Effective treatment depends on the type of mite involved and the severity of infestation. Key management steps include:
- Topical Medications â Spot-on parasiticides such as selamectin or moxidectin, lime sulfur dips, medicated shampoos.
- Systemic Therapy â Oral or injectable medications like ivermectin or milbemycin.
- Ear Treatments â Cleansing with ceruminolytic agents, plus vet-approved parasiticides for otodectic mange.
- Supportive Care â Antibiotics for secondary infections, anti-inflammatory medications.
- Environmental Decontamination â Washing bedding, cleaning grooming tools, and vacuuming carpets/furniture to remove lingering mites.
- Quarantine â Isolating infected cats to prevent spread during treatment.
Follow-up veterinary appointments are necessary to confirm treatment success and prevent re-infestation. Never attempt home remedies or over-the-counter medications without veterinary advice, as mismanagement can worsen symptoms or toxicity risk.
Prevention: Protecting Your Cat from Mange
While not always preventable, several proactive strategies greatly reduce your catâs risk:
- Maintain Excellent Hygiene and Clean Living Environment â Frequent laundering of bedding, toys, and blankets.
- Regular Veterinary Check-Ups
- Isolate New or Sick Animals until disease status is confirmed.
- Control Outdoor Access and Contact with Strays â Limiting group contact lowers exposure risk.
- Support Overall Health â Good nutrition, immune support, and minimizing stress keep skin and immune system resilient.
For multi-cat households, infection can travel quickly, so early detection and vet care are essential.
Frequently Asked Questions (FAQs)
How do I know if my cat has mange?
If your cat is suffering from persistent itching, patchy hair loss, sores, or thickened/crusty skin, mange is possible. Because similar symptoms occur with fleas, allergies, and infections, only a veterinarian can accurately diagnose mange through physical examination and laboratory analysis of skin or ear samples.
Can I catch mange from my cat?
Some forms, such as notoedric or Cheyletiella mange, are zoonoticâthey can temporarily affect humans, causing itching or skin rashes. Proper veterinary treatment and environmental cleaning can prevent spread.
Is mange only found in stray or outdoor cats?
No, indoor cats can also contract mange, especially from new animals or contaminated environments. Ear mites are frequently passed to indoor cats when a new infected cat joins the home.
How quickly does mange spread?
Mange can spread rapidly among cats living in close quarters, particularly in unsanitary group settings like shelters, colonies, or multi-cat homes. Mites that survive in bedding or on grooming tools can transmit between animals even without direct contact.
What is the prognosis for cats with mange?
With timely and appropriate treatment, most cats recover fully from mange, regrowing their fur and returning to good health. Severe or advanced casesâespecially in immunocompromised or very young catsârequire prompt medical intervention to prevent serious complications.
When to Seek Veterinary Help
If you notice any unexplained changes in your cat’s skin, fur, or behaviorâsuch as itching, hair loss, redness, scabbing, or ear problemsâcontact your veterinarian promptly. Early diagnosis ensures faster recovery, prevents spreading, and protects other pets and humans. Online or telemedicine vet services can also help provide initial advice but should not replace diagnosis and treatment from a licensed professional.
