Mange in cats is a skin disease caused by microscopic mites that burrow into or live on the skin, triggering intense itching, hair loss, and crusty lesions. Several different mite species can cause mange in cats, and the type of mite determines how the disease looks, how contagious it is, and how it should be treated. While mange is more commonly discussed in dogs, cats get their own distinct forms, and some can spread to other pets or even to people in the household.
The Different Types of Mange in Cats
Unlike dogs, where sarcoptic mange dominates the conversation, cats deal with a wider cast of mite species. Each one behaves differently, targets different parts of the body, and presents its own diagnostic and treatment challenges. The most common culprit in cats is Notoedres cati, followed by ear mites (Otodectes cynotis), with Demodex mites and Cheyletiella species rounding out the list.1Research, Society and Development.

Notoedric Mange, the Most Common Form
Notoedres cati is often called “feline scabies” because it behaves much like the Sarcoptes mite does in dogs. It burrows into the outer layers of a cat’s skin, laying eggs inside tiny tunnels. The immune response to the mite and its waste products is what drives the misery. Affected cats typically develop thick crusts, flaky and thickened skin, patchy hair loss, and relentless scratching. The lesions tend to start on the ear margins and face before spreading to the legs and sometimes the rest of the body.3PubMed Central. Notoedres cati in cats and its management
Because the face and ears are affected early, notoedric mange can give a cat a distinctive “lion-face” look, with heavy crusting around the nose, forehead, and ear tips. Cats will scratch and rub their faces on furniture aggressively, sometimes causing secondary wounds and bacterial infections. The disease is highly contagious between cats through direct contact, so one infected cat in a multi-cat household can spread it quickly.
Ear Mites and Otodectic Mange
Ear mites (Otodectes cynotis) are probably the most widely recognized mite problem in cats, especially in kittens. Technically, an ear mite infestation is a form of mange, though many cat owners think of it as a separate condition. The mites live inside the ear canal and feed on skin debris and ear wax, producing a characteristic dark, crumbly discharge that looks like coffee grounds. Cats with ear mites shake their heads frequently and scratch at their ears, and heavy infestations can lead to secondary ear infections.
One practical concern with ear mites is how long they survive away from the cat. Research on off-host survival found that at cooler temperatures, around 10°C, the mites can live for over two weeks. At warmer temperatures closer to 34°C, they die off within about five to six days. Under natural environmental conditions, the maximum survival observed was about 12 days.4PubMed. Otodectes cynotis (Acari: Psoroptidae): examination of survival off-the-host under natural and laboratory conditions This means bedding, cat trees, and shared resting spots can harbor mites for nearly two weeks, so cleaning or vacating those areas matters when you are treating an infestation.
Demodectic Mange in Cats
Demodex mange in cats is less common than in dogs but more complicated. Three species of Demodex mites have been identified in cats, and they can cause itching, a bumpy rash pattern called miliary dermatitis, and hair loss from overgrooming.5PubMed Central. Feline demodicosis: a consideration in the itchy or overgrooming cat The two you are most likely to encounter are Demodex cati and Demodex gatoi, and they behave very differently from each other.
Demodex cati is the more “traditional” form. Like the Demodex mite that causes mange in dogs, it lives deep inside hair follicles and is typically associated with an underlying immune problem. Cats with feline immunodeficiency virus (FIV), feline leukemia, diabetes, or cats on long-term immunosuppressive drugs are at higher risk. In a healthy cat with a functioning immune system, these mites usually stay in low numbers and cause no symptoms.
Demodex gatoi is the odd one out. Instead of living in hair follicles, it lives in the superficial keratin layer of the skin, and unlike most demodectic mites, it is contagious between cats.6PubMed Central. Demodex gatoi-associated contagious pruritic dermatosis in cats–a report from six households in Finland In multi-cat households, one cat may be intensely itchy with scaling, broken hairs, and self-inflicted scratches, while another cat in the same home may carry the mites without showing any symptoms at all. That silent carrier situation makes eradication tricky, because an asymptomatic cat can keep reinfecting its housemates.7PubMed.

Walking Dandruff
Cheyletiella mites cause a condition sometimes called “walking dandruff” because the large, white mites are occasionally visible to the naked eye moving across a cat’s coat. The classic sign is heavy flaking and dandruff, especially along the back, with mild to moderate itching. The condition is more common in long-haired breeds. A case study of a Persian cat with Cheyletiella showed alopecia at the base of the tail, skin flaking, and mild itching, and the mites were identified from microscopic examination of a skin scraping.8PubMed Central. An unusual case of Cheyletiellosis in a Persian cat and its therapeutic management
Cheyletiella is one of the more treatable forms of mange. In a study of 15 cats from the same household treated with selamectin (the active ingredient in Revolution), all cats were clear of symptoms by 60 days, and there was no recurrence a year later.9PubMed Central. Efficacy of selamectin in the treatment of naturally acquired cheyletiellosis in cats The ease of treatment is good news, but the condition still requires a vet visit for proper diagnosis because the symptoms overlap with allergies, ringworm, and other skin problems.
Who Gets Mange and Why
Mange can affect any cat, but some cats face much higher odds than others. A study looking at risk factors for feline scabies found that outdoor access and crowded living conditions were the biggest contributors. Cats living outdoors were roughly five times more likely to develop scabies than indoor-only cats. Even more striking, cats living in groups had about 17 times the odds of getting scabies compared to cats living alone.10Jurnal Kajian Veteriner. Risk Factors Associated with Feline Scabies at a Veterinary Clinic in Municipal Pekanbaru That finding aligns with common sense, since mange mites usually spread through direct contact or shared environments, so shelters, feral colonies, and multi-cat households are natural hotspots.
Fur length, on the other hand, did not meaningfully affect the risk. The same study found no statistically significant difference between long-haired and short-haired cats. This is worth knowing, because some owners assume long-haired cats are more vulnerable due to their dense coats trapping mites. The data do not support that assumption.
For demodectic mange specifically, the story is different. Because Demodex cati tends to flare in immunosuppressed cats, the risk factors are not about exposure but about the individual cat’s health. Older cats with chronic disease, cats on corticosteroids, and cats with retroviral infections are the ones who tend to develop clinical demodicosis. Demodex gatoi, by contrast, can affect healthy cats and spreads through contact, so its risk factors look more like those for notoedric mange: close quarters, shared grooming, and multi-cat living.
How Mange Is Diagnosed
The standard first step is a skin scraping. A vet uses a blade to gently scrape the surface of the affected skin, collects the material onto a slide, and examines it under a microscope for mites, eggs, or mite fecal matter. For notoedric mange, an acetate tape impression test, where clear sticky tape is pressed onto the skin and then examined, performs comparably to traditional skin scraping. One study found a strong correlation between the two methods, and in a couple of cases the tape test actually picked up mites that the scraping missed.11PubMed Central. Acetate tape impression test for diagnosis of notoedric mange in cats
Demodex gatoi presents a particular diagnostic headache. Standard skin scrapings frequently come up negative even when the cat is infested, because the mite lives in such a shallow layer of skin that it is easily missed. Researchers have noted that multiple diagnostic methods, including PCR testing, should be used to improve the chances of detection.12PubMed. Prevalence of Demodex gatoi in shelter and feral cats in a southeastern region of the United States Some vets will start a trial treatment based on clinical suspicion alone if the symptoms fit and other causes have been ruled out, rather than waiting for a definitive positive scraping.
For ear mites, diagnosis is usually more straightforward. The dark, crumbly ear discharge is distinctive, and a vet can often see mites moving under a magnifying otoscope. A sample of the ear debris examined under a microscope confirms the presence of Otodectes.
Treatment Options
Treatment depends on which mite is involved, but the veterinary toolbox has expanded considerably in recent years. Newer drugs in the isoxazoline class, including sarolaner, fluralaner, and esafoxolaner, have shown strong results against multiple mite species in cats. For ear mites, these medications along with macrocyclic lactones like selamectin, eprinomectin, and moxidectin can achieve full parasitological cure with relatively few side effects.13The Canadian Veterinary Journal. The most effective systemic treatment in cats with otodectic mange: A critically appraised topic
For demodectic mange, the evidence base is still growing. A consensus guideline from the World Association for Veterinary Dermatology noted that the strongest treatment evidence for feline demodicosis involves lime sulfur dips and amitraz baths, though these are messy and unpleasant for both cat and owner.14PubMed. Diagnosis and treatment of demodicosis in dogs and cats: Clinical consensus guidelines of the World Association for Veterinary Dermatology Isoxazolines are increasingly being used as a more practical alternative. A case report described a single spot-on application of fluralaner successfully treating localized Demodex cati infection, including mites in the ear canal.15PubMed Central. Effectiveness of a fluralaner spot-on formulation in a case of feline demodicosis due to Demodex cati For a disease that historically required weeks of dipping, a single topical application is a meaningful improvement.
A few important caveats on treatment:
- All cats in the household need treatment. Even symptom-free cats can be carriers, especially with Demodex gatoi, ear mites, and Cheyletiella. Treating only the visibly sick cat invites reinfection.
- Environmental cleanup matters for ear mites. Given their ability to survive off the host for up to about 12 days, bedding should be washed and resting areas cleaned during the treatment period.
- Underlying disease must be addressed. If a cat develops Demodex cati mange, the mites are often a signal that something else is wrong. Testing for FIV, feline leukemia, and metabolic diseases like diabetes is standard practice in these cases.
- Never use dog mange treatments on cats. Some products safe for dogs, particularly those containing permethrin, are toxic to cats and can be fatal. Only use medications specifically prescribed or approved for cats.
Can You Catch Mange From Your Cat?
Some forms of feline mange are zoonotic, meaning they can temporarily affect humans. In a report of four cats with sarcoptic mange, the in-contact human owners developed itchy papular skin lesions in three of the four cases.16PubMed Central. Crusted scabies (sarcoptic mange) in four cats due to Sarcoptes scabiei infestation Cheyletiella is also a known zoonotic offender: in the Persian cat case described earlier, the owner and her family members developed itchy lesions on their own skin.17PubMed Central. An unusual case of Cheyletiellosis in a Persian cat and its therapeutic management Notoedric mange can also cause temporary itching in people who handle infected cats.
The key word is “temporary.” Cat-specific mites are not well adapted to completing their life cycle on human skin. They can burrow in or bite enough to cause an itchy rash, but they typically cannot reproduce on a human host. Once the cat is treated and the source of mites is eliminated, the human symptoms resolve on their own, usually within a few weeks. That said, if you are developing unexplained itchy bumps while your cat is showing skin problems, mention both facts to your doctor and your vet, since they are almost certainly connected.
Why Mange Gets Mistaken for Other Conditions
Mange can look remarkably similar to several other feline skin diseases, which is why a vet visit with proper diagnostics matters. Ringworm, a fungal infection that is extremely common in cats, also causes hair loss, crusting, and scaly patches. Allergic dermatitis from flea bites, food sensitivities, or environmental allergens produces intense itching and overgrooming that can mimic the hair loss seen in mange. Bacterial skin infections can create crusts and sores that overlap visually with notoedric mange.
The overlap is especially confusing with Demodex gatoi, because the primary symptom is often just itching and overgrooming without the dramatic crusting seen in notoedric or sarcoptic mange. A cat who is constantly licking its belly bald might have a food allergy, psychogenic overgrooming, or a D. gatoi infestation, and telling them apart without testing is unreliable. The difficulty of detecting D. gatoi on skin scraping compounds the problem, which is why some dermatologists will trial-treat for the mite even with negative test results if the clinical picture fits.
Sarcoptic Mange in Cats
Sarcoptic mange deserves a separate mention because its rarity in cats leads to interesting confusion. In dogs and many wild mammals, Sarcoptes scabiei is a major parasite that has been classified into host-associated varieties, like S. scabiei var. canis for dogs. However, researchers have pointed out that the historical classification of Sarcoptes varieties does not actually include a S. scabiei var. felis, despite domestic and wild felids clearly being susceptible hosts.18PubMed Central. Sarcoptic mange in Felidae: does Sarcoptes scabiei var. felis exist? A first molecular study This gap in the taxonomy reflects how understudied sarcoptic mange is in cats compared to dogs. When it does occur, the clinical picture can be severe, with heavy crusting and skin thickening that resembles the notoedric form. The cases that have been documented sometimes involve cats in contact with infected dogs or wildlife, suggesting cross-species transmission plays a role.
Living With a Cat Being Treated for Mange
If your cat has been diagnosed with a contagious form of mange, the treatment period typically involves a few weeks of management at home. Isolating the affected cat from other pets, when practical, reduces the chance of spreading mites. Washing bedding, blankets, and fabric covers in hot water helps eliminate mites in the environment. For ear mites specifically, shared resting spots should be cleaned or left unused for at least 12 days based on how long the mites can survive off a host.19PubMed. Otodectes cynotis (Acari: Psoroptidae): examination of survival off-the-host under natural and laboratory conditions
Cats often look worse before they look better during treatment. As mites die, the inflammatory response in the skin can temporarily flare, and loosening crusts may make the coat look rougher for a few days. Secondary bacterial infections sometimes need a short course of antibiotics alongside the anti-mite treatment. Your vet will likely want a follow-up skin scraping a few weeks into treatment to confirm that mites are being cleared. For Demodex cati, follow-up is especially important because the underlying immune issue that allowed the mites to flourish may need ongoing management.
Preventing mange mostly comes down to limiting exposure. Indoor cats rarely encounter mange mites unless another pet in the household brings them in. New cats entering the home, whether from a shelter, a breeder, or found outdoors, should ideally be examined by a vet before being introduced to resident cats. Monthly flea and parasite preventatives that include mite coverage, like selamectin-based products, provide a useful layer of protection. None of these steps guarantees your cat will never encounter mites, but they significantly reduce the odds.
