What is a cat’s mange?
“Milk source” is a general term for an infectious skin disease characterized by intense itching, skin redness, and hair loss (alopecia) caused by parasitic mites. Although scabies is a type of dermatitis (i.e. inflammation of the skin), it is special in that its underlying cause has been clearly identified as an infestation with mites.
Many other types of skin conditions may resemble scabies (that is, reddened skin with hair loss), but they require different methods of diagnosis and treatment.
Quick Overview: Feline Distemper
other names: Notoedric mange, sarcoptic mange, demodectic mange
common symptoms: Hair loss (small patches or large areas), scabs, scabs, red skin areas, skin sores, itching. Many cats have lesions on their ears, legs, and faces.
diagnosis: A sample collected from an affected area called a skin scrape is examined under a microscope.
diagnosed as a cat: Rarely (all forms of milk)
need to continue taking medication: No
available vaccines: No
Treatment programs: Several oral and topical medications are effective against mites. This includes some parasite prevention products, including Revolution (sellamectin), Interceptor (milbemycin oxime), Advantage Multi (moxidectin/imidacloprid), and Bravecto (flurelan), among others.
home remedies: Can be impregnated with lime sulfur.
Causes of Mange in Felines
Three types of parasitic mites can cause different types of mange in cats.
1. Notoedric Mange
Sometimes called “feline scabies,” this is the most common type of mange in cats. The condition is caused by a mite called Notoedres cati, which is invisible to the naked eye and has a diameter of 200-250µm (ie 0.2 to 0.25 mm: the size of a pinhole).
Under the microscope, mites are tiny, oval-shaped white bugs with three pairs of short legs in the larval stage and four pairs in the nymph and adult stages. The mites are contagious and spread from cat to cat by direct contact, causing extreme itching when the mites burrow into the skin.
Adult female mites lay their eggs deep in the skin, and the larvae hatch and move to the surface of the skin, where they develop into the nymph stage and then transform into adults. All stages of the mite feed on the skin, causing itching due to damage caused by feeding. The full life cycle from egg to adult takes three weeks.
Notoedric mange is most common in cats with weakened immune systems (such as kittens). This type of mange is rare in cats: less than 0.1% of cats in the US suffer from the skin condition, and in the UK it has not been diagnosed at all for more than fifty years.
Demodex mites are found in many mammals (including cats, dogs, and humans). They start out as normal, harmless, symbiotic parasites that live in hair follicles, sebaceous glands, and the surface layer of the skin.
Only when there is some kind of immune deficiency in the host, the mites will start to multiply and cause skin diseases. Demodex mites are cigar-shaped, visible only under a microscope, and are about 350 microns or 0.35 mm long.
The eggs are also elongated and oval; they hatch into six-legged larvae, then eight-legged nymphs, and then eight-legged adults. Demodex mites are rare in cats, accounting for less than 0.04 percent of dermatology cases in the United States.
Sarcoptic mange is caused by a mite that normally lives on dogs: Sarcoptes scabiei var canis. The mite is rare in cats and only shows up if they have had close contact with an infected dog or fox. These mites are small round white mites, slightly larger than Notoedres mites, 300-400µm (0.3-0.4mm) in diameter. Likewise, larvae have three pairs of legs while adult mites have four pairs.
other ectoparasitesinclude ear mites (canine ear mites) and walking dandruff (cheyletiella) may look similar to these mites microscopically, but they cause a different type of ear or skin disease and are not usually classified as “scabies mites.”
ringworm Bald, reddened areas can result, similar to mange, but this is caused by a fungal infection, so requires a completely different approach.
Mange Symptoms in Cats
Mange, by definition, causes itching (itching), reddening of the skin in the affected area, and hair loss. Cats often develop dandruff-like scales with crusty buildup on their skin. Different mites cause different patterns of location on the affected skin.
- Nanyang Milk Often affects the ears, neck and forelimbs.
- Demodex (also known as demodicosis) can be generalized (whole body) or localized (such as a mite Demodex feline around the eyes, head, nose, or neck, or along the back, abdomen, or extremities Another type of mite, Demodex).
- Scabies Tends to be more general, affecting the feet, sides of the body, hind legs, face, ear tips, and tail
Diagnosis of feline distemper
If your cat is showing signs of scabies, you need to see your local DVM veterinarian. A sample needs to be taken from the cat (usually a skin scraping, but sometimes an acetate tape imprint on the fur is sufficient to identify notododes or demodex mites).
Examination of the sample under a microscope is always required to definitively identify the pathogenic mite.
Mange for Healing Cats
Treatment depends on the type of mite infestation, and your veterinarian will prescribe the appropriate medication.
Treatment options include:
- Selamectin As a topical topical treatment (a product owners may be familiar with as a preventive treatment for fleas and heartworms)
- Milbemycin oxime as an oral drug
- Doramectin as a weekly injection
- Lime sulfur immersion topical therapy
- Ivermectin as an oral or injectable drug
- Amitra As a weekly soak, let the cat dry without rinsing.
- Moxidectin/Imidacloprid (promote) as an on-site topical formulation
- Fluralaner (Bravector) as an oral drug
- Combination products Fipronil 8.3%, (S)-Methoprene 10%, eprinomectin 0.4%, and Praziquantel 8.3% (wide line)
The initial mange problem may be complicated by a secondary bacterial infection of the itchy skin, so antibiotics and other treatments for skin infections may also be needed.
All of these products can be toxic if used incorrectly and must therefore be administered as part of a broad, specific treatment program as prescribed and directed by your veterinarian.
frequently asked questions
Can apple cider vinegar kill milk?
Despite what some websites suggest, apple cider vinegar by itself is unlikely to cure mange in cats, and a proper mite-killing regimen as prescribed by your veterinarian is far more effective.
Is mange in cats contagious to humans?
Notoedric and demodectic mites are species-specific and therefore cannot infect humans, whereas meat mites may transiently infect humans.
How do I treat my cat’s mange at home?
There are no effective home remedies for mange in cats: the only way to effectively address this rare problem is with prescription products available from your veterinarian.
I am broadly interested in how human activities influence the ability of wildlife to persist in the modified environments that we create.
Specifically, my research investigates how the configuration and composition of landscapes influence the movement and population dynamics of forest birds. Both natural and human-derived fragmenting of habitat can influence where birds settle, how they access the resources they need to survive and reproduce, and these factors in turn affect population demographics. Most recently, I have been studying the ability of individuals to move through and utilize forested areas which have been modified through timber harvest as they seek out resources for the breeding and postfledging phases. As well I am working in collaboration with Parks Canada scientists to examine in the influence of high density moose populations on forest bird communities in Gros Morne National Park. Many of my projects are conducted in collaboration or consultation with representatives of industry and government agencies, seeking to improve the management and sustainability of natural resource extraction.
