# Mange in Cats: Symptoms, Types, and Treatment

Mange in cats is a skin disease caused by microscopic burrowing mites. The most common form in cats, notoedric mange, produces intense itching, hair loss, and thick crusts that start on the head and ear edges. It is contagious to other cats and to people. A cat with mange needs a veterinarian, because the mites that cause it are identified under a microscope and the drugs that kill them are prescription-only in the United States. Left untreated, mange can progress to deep skin infection, weight loss, and serious illness. The good news is that modern antiparasitic spot-on products clear the infestation reliably, and most cats improve within two to four weeks of a single treatment [1][2].

This guide explains the three mange mites that matter in cats, how each one looks and behaves, how veterinarians confirm the diagnosis, and which treatments are used and why. It also covers what you can do at home, what to avoid, and when to call your vet.

## At a Glance: What to Do If You Suspect Mange

1. Look for the pattern. Itching, hair loss, and crusting that begins on the face, ears, or head is the classic picture of notoedric mange in cats [3].
2. Do not treat at home with leftover or over-the-counter products. Some antiparasitic drugs are dangerous in cats, and the wrong product can cause a seizure or death.
3. Separate the affected cat from other cats, dogs, and children until a veterinarian examines it.
4. Book a veterinary visit. Bring a note of when signs started and whether any people or other pets in the home are itchy.
5. Expect skin scrapings, possibly several. Your veterinarian may also pluck hairs or examine ear wax [3][4].
6. Expect a prescription spot-on product. Owners do not need to bathe, dip, or clip the cat unless the veterinarian advises it.
7. Recheck. A follow-up visit confirms the mites are gone and tracks healing [5].
8. Treat in-contact pets if the veterinarian recommends it, because notoedric mange spreads readily between cats [6].

## What Is Mange in Cats?

Mange is the common name for skin disease caused by mites. In cats, the term covers several different mites with very different behavior. Some burrow into the skin. Some live in hair follicles. Some simply live on the surface and feed on debris. Each type produces a different pattern of signs, a different level of itchiness, and a different risk to other animals and people.

A mange mite is not a worm, a fungus, or an allergy, although the intense itching of mange is largely an allergic reaction to the mites and their waste products. Research on mange mite proteins shows that these organisms carry many distinct proteins that act as allergens. In a laboratory study of mite extracts, the mange mite that affects cats, Notoedres cati, produced 36 protein fractions, more than the mange mites of cattle, sheep, and pigs tested in the same study [7]. That large protein load helps explain why the immune system reacts so strongly and why cats scratch themselves raw.

Mange is also not the same as fleas or ear mites, although all three can occur together. In one report, two cats with notoedric mange also carried fleas and a lungworm infection, and mange mites were found in every diagnostic test performed, including coat brushing, skin scrapings, and ear wax examination [4]. That overlap is one reason a veterinarian examines the whole cat rather than just the itchy patch.

There are three mange mites that primarily affect cats: Notoedres cati, Demodex gatoi, and Demodex cati. A fourth mite, Sarcoptes scabiei, normally infects dogs and other mammals but can also infest cats. Recognizing which mite is involved matters, because contagion risk and treatment differ.

### Notoedres cati (Feline Scabies)

Notoedres cati is the classic mange mite of cats. It causes a disease called notoedric mange, also known as feline scabies [5]. This is the form most cat owners mean when they say a cat has mange.

Key features:

- Location. Signs start on the head, ears, and face and can spread to the neck and body. One case report described a cat with extensive neck and facial skin lesions plus bilateral inflamed waxy ear infections [3]. Another series found the concave and convex surfaces of the ear flaps were the first and most severely affected areas [8].
- Itch. Notoedric mange is intensely itchy. The burrowing of the mite causes intense itching that leads to self-mutilation and secondary bacterial infection if untreated [9].
- Contagion. It spreads easily between cats through direct contact. Notoedres cati is also contagious to other animals and to humans [6].
- Who gets it. It is most often seen in stray and outdoor cats with no parasite prevention [3][4].

The damage from notoedric mange comes from two sources. The mite itself burrows in the skin, and the cat's allergic reaction to the mite does most of the visible harm. This is why a cat can look severely diseased even when the number of mites is modest.

### Demodex gatoi

Demodex gatoi is a short-bodied follicle mite. Unlike Demodex cati, it is contagious between cats and it itches. It tends to cause more generalized skin disease rather than staying confined to the head.

Key features:

- Itch. Cats with Demodex gatoi are typically itchy.
- Contagion. It spreads from cat to cat and can move through a household of cats.
- Distribution. It often causes widespread hair loss rather than a single patch.

Feline demodicosis is described as a rare parasitic skin disease, and the clinical signs can range from mild and localized to severe and generalized. Signs include hair loss, redness, small spots, itching, and darkening of the skin [10]. Because Demodex gatoi is contagious and often widespread, a veterinarian may recommend treating all cats in the home.

### Demodex cati

Demodex cati is the other follicle mite of cats. It usually behaves very differently from Demodex gatoi.

Key features:

- Itch. Demodex cati is usually not itchy.
- Contagion. It is generally not considered contagious between cats.
- Underlying cause. It is often associated with a weakened immune system or another illness.

One case report describes a young cat that was positive for feline immunodeficiency virus and was diagnosed with demodicosis at the same time as a serious fungal infection [11]. This pattern, in which Demodex cati appears alongside another disease or immune problem, is typical. When a veterinarian finds Demodex cati, they often look for a reason the cat's immune system is not controlling the mite on its own.

### Sarcoptes scabiei (From Dogs and Wildlife)

Sarcoptes scabiei is the mite that causes sarcoptic mange, or scabies, in dogs and many other mammals, including humans. It can also infest cats [12]. Cats are generally considered non-permissive hosts, meaning the mite does not reproduce well on them and the disease is often self-limiting [12]. Even so, severe cases occur.

Key features:

- Source. Cats usually pick it up from a dog with sarcoptic mange, from foxes, or from a contaminated environment [13].
- Itch. Itching in cats is variable. In one series of four cats, itching was not a prominent feature and was considered absent in three of the four [13]. In a later series of three cats, all three were itchy [14].
- Lesions. Crusted lesions on the ears, nose bridge, and sometimes the paws and tail are common [8].
- Contagion to people. In-contact people can develop itchy skin bumps. In one series, all five owners of affected cats developed itchy red bumps on their arms or thighs [8].

Because Sarcoptes can pass between species, a cat with sarcoptic mange is a household concern, not just a cat concern.

## Mite Comparison Table

| Mite | Typical Location | Itch Level | Contagious Between Cats | Risk to People | First-Line Treatment Approach |
|--|--|--|--|--|--|
| Notoedres cati | Head, ears, face, neck | Intense | Yes, highly | Yes, zoonotic | Prescription spot-on miticide |
| Demodex gatoi | Often generalized | Itchy | Yes | Not a known zoonosis | Prescription miticide, treat all cats |
| Demodex cati | Localized or generalized | Usually not itchy | No | Not a zoonosis | Treat the mite and look for underlying disease |
| Sarcoptes scabiei | Ears, nose, paws, tail | Variable | Yes, from dogs or wildlife | Yes, zoonotic | Prescription miticide, treat in-contact animals |

This table is a starting point for understanding what a veterinarian is looking for. It is not a self-diagnosis tool, because the appearance of mange overlaps with allergies, fungal infections, and other skin diseases.

## Symptoms of Mange in Cats

The signs of mange in cats fall into a few clear groups.

### Itching and Self-Trauma

Itching is the single most common reason owners seek help. In notoedric mange it is severe. Cats scratch, chew, and rub at their face and ears until the skin is raw. The intense scratching is a direct result of the burrowing mite and the allergic response to it [9]. A cat that scratches the head and neck constantly needs a veterinary exam, especially if the cat goes outdoors or lives with other cats.

### Hair Loss

Hair loss follows the itching. It may be patchy or widespread. In one severe case, a stray cat had hair loss on both sides of the body with crusted and scaly lesions [12]. In another report, cats with mange involving the ears had hair loss on the ear flaps [8].

### Crusts, Scales, and Thickened Skin

Crusting is a hallmark of notoedric mange. A recent case report described a cat with severe itching, hair loss, thick crusts, and a deep skin infection, with the maximum severity score on a clinical mange scale [3]. Long-standing sarcoptic mange in cats can look like the crusted form of scabies seen in people, with heavy scale and crust [13].

### Head and Ear Changes

The head is involved early in most feline mange. The margins of the ears, the bridge of the nose, and the face are common sites [8]. Ear wax changes can also occur. In one cat, notoedric mange caused inflamed waxy ear infections on both sides [3]. Dark, crumbly debris or redness in the ear canal is often mistaken for ear mites, so a veterinarian examines ear wax under the microscope to separate the two problems.

### Redness, Spots, and Darkened Skin

Red skin, small spots, and patches of darkened skin are described in feline demodicosis [10]. These changes are not specific to mange, which is why scrapings are needed.

### Systemic Signs

Mange is not always limited to the skin. The cat in the recent severe case report had signs of systemic illness, and blood work showed an inflammatory response [3]. Weight loss and poor body condition can occur, especially in cats with long-standing disease and heavy parasite burdens [4]. A cat with mange that has stopped eating or is losing weight needs prompt care.

### People and Other Pets Becoming Itchy

This is one of the most useful clues. If a person in the home develops itchy bumps, or a dog has been diagnosed with sarcoptic mange, the cat's skin disease is more likely to be sarcoptic or notoedric mange [13][8]. Household itching should be mentioned to the veterinarian during the visit.

## How Mange Spreads

The contagious mange mites spread by direct contact between animals. Notoedres cati is highly contagious between cats and can also infest other animals and humans [6]. Demodex gatoi spreads between cats as well. Sarcoptes scabiei reaches cats through contact with an affected dog, fox, or contaminated space [13].

Demodex cati is different. It is generally not passed between cats and is more often linked to a cat's own immune status [11].

Mites do not fly or jump. They move from body to body, or from a contaminated surface to a body. This is why a cat recently adopted from a shelter, a stray cat brought indoors, or a cat that lives with a roaming dog is at higher risk. Because mites can survive for a time away from the host, washing bedding and vacuuming the areas the cat uses is a reasonable step while treatment is underway.

## How Veterinarians Diagnose Mange in Cats

Diagnosis is not based on how the skin looks. It is based on finding the mite. Several tests are used, and sometimes more than one is needed.

### Skin Scraping

Skin scraping is the primary test. The veterinarian uses a blade to scrape the surface of the skin until it oozes slightly, then examines the material under a microscope. In notoedric mange, scrapings from the ears and head are often fruitful [3]. In sarcoptic mange, deep skin scrapings reliably find the mite, and scrapings become negative after effective treatment [8]. Scrapings are also how Demodex mites are found.

### Hair Plucking

Pulling a few hairs from an affected area can bring follicle mites to the surface. This is useful when the veterinarian suspects Demodex, because those mites live in hair follicles rather than burrowing into the surface layer.

### Ear Wax Examination

Notoedres cati can be found in ear wax, especially when the cat has an inflamed waxy ear infection [3][4]. Ear wax examination is quick and can confirm the diagnosis when skin scrapings are borderline.

### Fecal Flotation

Mites can be swallowed when a cat grooms and then pass into the stool. Fecal flotation can therefore reveal mange mites. In one report, Notoedres cati mites were found in high numbers by every complementary test used, including fecal techniques [4]. A related approach is fecal PCR testing, which detects mite DNA in stool. A PCR assay for Notoedres cati was 100 percent specific and could detect as few as 1.9 mites per 200 micrograms of feces, with moderate sensitivity of 52.6 percent [9]. This test was developed for wild cats but illustrates why stool can carry the answer.

### Repeat Testing for Demodex gatoi

Demodex gatoi is notoriously hard to find. The mites are few, they live deep in follicles, and a single scraping often misses them. Multiple scrapings from several sites, combined with hair plucking, improve the odds. If a veterinarian strongly suspects Demodex gatoi based on the pattern of itchy, widespread hair loss and a history of other affected cats, treatment may be started even when the first scrapings are negative, with repeat testing later.

### Ruling Out Other Diseases

Because mange can look like allergies, fungal infections, or bacterial skin disease, veterinarians often run additional tests. Skin cytology looks for bacteria and yeast. In one cat with mange, cytology and other tests confirmed a deep bacterial infection alongside the mites [3]. In another case, a cat with demodicosis was also diagnosed with a fungal infection and FIV, which changed the treatment plan [11].

## Treatment of Mange in Cats

Treatment always has two parts. The first part kills the mite. The second part supports the skin, controls infection, and relieves suffering while the skin heals. A cat with severe mange may need antibiotics, pain or itch relief, fluids, and nutritional support in addition to the antiparasitic drug [3].

### Prescription Spot-On Products

The most practical and best-supported treatments for feline mange are prescription spot-on products applied to the skin between the shoulder blades. These products spread over the body and kill the mites. Several have been tested specifically in cats with notoedric mange.

**Selamectin and sarolaner.** A spot-on combination of selamectin and sarolaner was tested in client-owned cats with naturally occurring Notoedres cati. Cats were treated on days 0 and 30, and scrapings plus clinical scoring were done on days 0, 30, and 60. A single topical administration produced a significant reduction in live mite counts [5]. This product is one of the standard options for notoedric mange in cats.

**Esafoxolaner, eprinomectin, and praziquantel.** This topical combination was evaluated in a controlled study of 14 cats with notoedric mange. Cats received one spot-on dose. No live mites were recovered from any treated cat after treatment, indicating 100 percent efficacy from a single application. Clinical success rose from 14.3 percent at day 14 to 100 percent by day 42 and remained at 100 percent at day 56 [2]. A separate field study of 17 cats living in the same house found 100 percent efficacy, with no live mites from day 14 onward, and treated cats gained more weight than untreated cats by day 56 [15]. A case report of a severely affected cat also used this combination as part of successful treatment alongside antibiotics and supportive care [3].

**Imidacloprid and moxidectin.** A spot-on combination of imidacloprid and moxidectin was studied in 16 cats with natural Notoedres cati infestation. Treated cats received a single spot-on dose. At 28 days after treatment, the number of live mites in treated cats was zero, compared with an average of 2.8 mites in untreated controls. The resulting efficacy was 100 percent, and clinical cure based on skin lesion scoring was achieved at 28 days in all treated cats [6]. A separate field study of a topical formulation containing fipronil, moxidectin, and praziquantel reported 100 percent efficacy against Notoedres cati, ear mites, and lice within 3 days of a single dose, and the product was well tolerated [16].

**Tigolaner, emodepside, and praziquantel.** A single spot-on treatment with this combination was tested in cats naturally infested with Notoedres cati. All treated cats were free of mites at day 28, a 100 percent parasitological cure, and all were clinically cured by day 28 [1].

These products differ in the mites they target and in label claims, and not every product is approved for every indication in every country. Your veterinarian selects based on the mite identified, the cat's age and weight, other medications, and what is legally available.

### When More Than One Treatment Is Needed

Some products are given once, and others are repeated. In the selamectin and sarolaner study, treatment was applied on days 0 and 30 [5]. In one notoedric mange case, selamectin spot-on was given three times at 1- or 4-week intervals [4]. Treating sarcoptic mange in five cats used a moxidectin and imidacloprid spot-on every 2 weeks for three applications, with scrapings negative after the first application and clinical remission after the third [8]. The number of doses depends on the product, the mite, and how the cat responds.

### Older Injectable Options

Injectable avermectin drugs have been used for feline mange. Doramectin given under the skin cleared notoedric mange in five cats, with lesions receding one week after treatment and all five cats clinically normal at 15 days [17]. Ivermectin has also been used successfully in some cats with sarcoptic mange [14]. However, injectable avermectins carry real risk in cats. Doses that are safe in dogs can cause severe neurologic signs, including tremors, stumbling, and seizures, in cats. This class of drug should only be used by a veterinarian who has weighed the risk and who can monitor the cat. Do not use a dog's injectable parasite medication on a cat.

### Lime Sulfur

Lime sulfur is a topical treatment that has been used for feline mange and demodicosis. It is applied as a dip or rinse. In one report, a cat with severe crusted sarcoptic mange responded to topical lime sulfur treatment [13]. Lime sulfur has a strong odor, can stain, and requires repeated application, but it remains a useful option when other drugs are not suitable. It should be applied only on veterinary advice, with attention to the cat's eyes and any open sores.

### Why Ivermectin Is Risky in Cats

Ivermectin and related avermectins are not interchangeable between species. Cats are more sensitive than dogs to neurologic side effects from this drug class. Some cats carry a genetic change that makes them even more vulnerable. A veterinarian may still choose an avermectin when the benefit is clear and the cat can be watched closely, but the dose must be calculated precisely and the cat monitored for wobbliness, dilated pupils, drooling, or twitching. Never give a cat an injectable or oral antiparasitic intended for a dog.

### Why Treatment Failures Happen

Most treatment failures have a simple cause.

- The cat was treated once when the product required a second dose.
- Another cat in the home was not treated and reinfested the first cat.
- The owner used a product that does not kill mange mites, such as a flea-only product.
- The diagnosis was wrong and the actual problem is an allergy or fungal infection.

When a cat does not improve, the veterinarian usually repeats the scrapings and reviews the household treatment plan rather than simply switching drugs.

### Supporting Care During Treatment

Antiparasitic drugs kill mites, but they do not repair damaged skin overnight. Supportive care can include:

- Antibiotics for secondary bacterial skin infection. In one severe case, an oral antibiotic was part of the treatment plan [3].
- Anti-itch medication. In the same case, an anti-inflammatory drug was used to control severe itching [3].
- Skin care. Gentle cleansing and topical care support healing. That case used supportive skin care as part of successful management [3].
- Deworming and flea control. Many cats with mange carry other parasites. The cat in that case report also had roundworms, tapeworms, and a gut parasite and received treatment for them [3]. Another report found fleas and a lungworm alongside the mange mites [4].

## Zoonotic Risk: Mange Can Spread to People

Notoedres cati and Sarcoptes scabiei can both affect humans. Notoedres cati is contagious to other animals and to humans, although the mite does not complete its life cycle on people [6]. Sarcoptes scabiei is well known as a human scabies agent, and cats can act as a source.

Evidence of household spread is strong. In one series of five cats with sarcoptic mange, all five owners developed itchy red bumps on their arms or thighs, and the owners improved at the same time as the cats [8]. In a series of four cats, in-contact human carriers developed itchy skin bumps in three of the four cases [13]. An older report describes a person with scabies traced to a cat with Sarcoptes scabiei [18].

What this means for a household:

- If a cat is diagnosed with notoedric or sarcoptic mange, tell everyone who has close contact with the cat.
- Itchy bumps in people should be evaluated by a physician.
- People with weakened immune systems, young children, and the elderly are more vulnerable to skin mites.
- Treating the cat removes the source. Human symptoms usually fade once the animal is treated [8].
- Wash bedding, blankets, and grooming tools, and vacuum areas the cat uses.

Demodex gatoi and Demodex cati are not considered human pathogens, so a cat with demodicosis alone is not a risk to the family's skin.

## Preventing Mange in Cats

Prevention is straightforward and mostly about parasite control and limiting exposure.

- Use year-round parasite prevention prescribed by your veterinarian. The same spot-on products that treat mange also prevent it when used on schedule.
- Keep cats indoors where possible. Notoedric mange is most common in stray and outdoor cats [3].
- Quarantine new cats. A newly adopted cat or a stray brought indoors should be examined before mixing with resident cats.
- Check in-contact dogs. Sarcoptic mange in cats often traces to a dog with scabies or an area used by foxes [13].
- Watch for early signs. Mild itching at the ear edges and nose bridge is easier to treat than a full-body crusted infection.
- Treat the whole household when a contagious mite is confirmed. In one household outbreak, all cats were treated together, and the population recovered [17].

## Mange on Cats Treatment: What Owners Should Not Do

A few common home responses do more harm than good.

- Do not apply dog mange medication to a cat. Dog products can contain doses of avermectins that are toxic to cats.
- Do not use a homemade dip, oil, or cream. These can irritate broken skin and delay real treatment.
- Do not stop treatment early because the skin looks better. The mite may still be present.
- Do not treat only the itchy cat if the veterinarian says the mite is contagious. Untreated cats continue to spread mites.
- Do not delay treatment to see if it clears on its own. Notoedric mange does not resolve without treatment and can become severe [3].
- Do not assume a human family member has scabies from the cat without speaking to a doctor. Some itchy rashes in people have other causes.

## Recovery Timeline

Most cats improve noticeably during the first weeks of treatment. In the esafoxolaner combination studies, clinical success reached 100 percent by day 42 in one study [2] and treated cats were clinically improved with weight gain by day 56 in another [15]. In the imidacloprid and moxidectin study, clinical cure was reached at 28 days [6]. In a severe case with secondary infection, follow-up visits on days 8, 12, 15, and 21 showed progressive improvement, with full resolution of mange, ear infection, and deep skin infection by the end of treatment [3].

Hair regrowth is slower than itch relief. The skin may look calm before the coat fully returns, and full regrowth can take a month or more. Cats that were thin at diagnosis often gain weight as the condition resolves [15].

## Follow-Up and Recheck

A recheck appointment is part of treatment, not an optional extra. The veterinarian repeats skin scrapings to confirm no live mites remain and scores the skin lesions to track healing. In the selamectin and sarolaner study, rechecks were done at 30 and 60 days [5]. Other studies checked at 14, 28, 42, and 56 days [2][15]. If live mites are still present, or if the cat is not improving, the plan is adjusted. Skipping rechecks is one of the most common reasons a cat relapses.

## Limitations and When to Contact a Veterinarian

This article is educational and is not a substitute for veterinary diagnosis or treatment. Individual cats respond differently, and only a veterinarian who examines your cat can make a diagnosis and choose a treatment.

Contact a veterinarian right away if any of the following apply:

- Your cat is scratching until the skin bleeds or is unable to rest.
- The face, ears, or neck are swollen, crusted, or oozing.
- The cat has stopped eating or is losing weight.
- There is a bad smell from the skin or ears, which can signal infection.
- You have more than one cat and any of them have skin signs.
- A dog in the home has been diagnosed with or treated for sarcoptic mange.
- Any person in the home has itchy bumps or a rash.
- The cat is young, very old, pregnant, or has another illness such as FIV.
- The cat has been treated for mange and is not improving within the expected window.
- You are considering any injectable parasite drug for a cat. Call first.

For a cat with severe or long-standing disease, your veterinarian may recommend blood work, skin cytology, or testing for other infections before or during treatment [3][11].

## Frequently Asked Questions

### How do I know if my cat has mange or just allergies?

You cannot reliably tell from appearance alone. Mange must be confirmed by finding mites in skin scrapings, hair plucks, or ear wax [3]. Allergies, fungal infections, and bacterial skin disease can look almost identical. A veterinary exam with skin testing settles the question.

### Is mange in cats contagious to humans?

Notoedres cati and Sarcoptes scabiei can affect people. In-contact people develop itchy skin bumps in many cases, and in one series all five owners of affected cats were affected [8]. Demodex mites of cats are not considered human pathogens.

### How is mange on cats treated?

Veterinarians use prescription spot-on antiparasitic products. Several have demonstrated 100 percent efficacy against Notoedres cati in controlled studies, including combinations containing selamectin, moxidectin, esafoxolaner, or tigolaner [1][2][16][5][6]. Injectable drugs and lime sulfur dips are used in some situations, but only under veterinary guidance.

### Can I use my dog's mange medicine on my cat?

No. Some antiparasitic drugs that are safe in dogs cause serious neurologic side effects in cats. Injectable avermectins in particular carry real risk. Always ask a veterinarian before giving any parasite medication to a cat.

### How long does mange treatment take?

Most cats improve within two to four weeks, and clinical cure is often documented by day 28 to 42 [2][6][15]. Complete hair regrowth can take longer. Recheck visits confirm that no live mites remain.

### Why did my cat get mange?

Most cases come from contact with an affected animal or a contaminated environment. Notoedric mange is most common in stray and outdoor cats [3]. Sarcoptic mange usually traces to a dog with scabies or an area used by foxes [13]. Demodex cati often appears when a cat's immune system is weakened by another illness [11].

### Do I need to treat my other cats?

Often yes. Notoedres cati and Demodex gatoi spread between cats, so a veterinarian may recommend treating every cat in the home [6]. In one household outbreak, all cats were treated, and the group recovered [17].

### Do I need to clean my house if my cat has mange?

Yes. Wash bedding and grooming tools and vacuum areas the cat uses. Mites can survive away from the host for a time, and cleaning supports the treatment by reducing the chance of reinfestation.

Sarcoptic mange usually traces to a dog with scabies or an area used by foxes. Demodex cati often appears when a cat's immune system is weakened by another illness."
