Demodectic mange in cats is an inflammatory skin disease that can cause itching, excessive earwax, head shaking, sores and hair loss. Various microscopic organisms that can infect your cat’s skin Demodex caused by mites.

What Is Demodectic Mange in Cats?

Demodicosis is a parasitic skin condition caused by Demodex mites. These microscopic mites can be found on the skin of all animals, but in some cases they multiply excessively, causing clinical signs. This increase is usually associated with a suppressed immune system, although this is not always the case.

Although demodicosis is more common in dogs than cats, there are two types of Demodex mites that can infect cats: Demodex cati and Demodex gatoi. D. cati is typically found in hair follicles, while D. gatoi is more likely to live on the skin surface. Cats of all breeds and ages can be affected by Demodex mites. Demodex mites can also infect other animals in your home, but mites are species specific. This is Demodex affecting your dog. means that the mites cannot pass to cats and vice versa.

Demodex mites are species specific. Each Demodex mite species has only one host species on which it can live. This means that an infected dog cannot transmit Demodex mites to a cat and vice versa. In addition, Demodex mites found on cats and dogs do not infect humans.

Symptoms of Demodectic Scabies in Cats

Demodex mites may be associated with localized or generalized disease. Signs vary depending on the type of mite involved.

Demodex Gatoi Symptoms

Demodex gatoi The most common symptom is itching/over-care, which can lead to hair loss and skin flaking. You may also see crusts and sores on your cat as a result of too much licking and scratching. D. gatoi often causes severe itching, inflammation of the skin, and crusting of the trunk and limbs. In some cases, cats may develop ulcers on the lips or small crusts on the whole body (military dermatitis). In most cases, skin problems associated with D. gatoi are clinically indistinguishable from allergic skin disease. Therefore, the possibility of demodicosis should be considered in any cat suspected of having an allergic skin disease. Some cats infected with D. gatoi may be completely asymptomatic without visible skin lesions.

Demodex Cati Symptoms

from Demodex cati Skin problems caused by skin problems may be limited to a single area or may spread throughout your cat’s body. Common skin problems include redness, scaling, crusting, and hair loss. Itching can range from mild to severe. In some cats, excessive ear build-up and ear irritation/head shaking may be the only symptoms. D. cati is often associated with hair loss, skin inflammation, and crusting. Skin lesions may be itchy, but this is not always the case. In some cases, cats may only have localized skin problems, usually on the face, head and neck. In other cases, the lesions may spread to cover the entire body. D. cati can also cause recurrent ear infections.

Contagion of Demodectic Scabies in Cats

D. cati is not contagious and cannot be spread among cats. Cases of localized infection do not necessarily indicate an underlying cause, but generalized infection may indicate underlying immune suppression that allows the mite to grow out of control. In cases of generalized D. cati infestation, your veterinarian may recommend testing for feline leukemia virus, feline immunodeficiency virus, or other immunosuppressive conditions. Additionally, D. cati may be associated with drugs that can suppress the immune system; Your veterinarian will take a thorough history to make sure your cat is not taking any medications that could cause this condition.

D. gatoi is contagious to other cats. Because some cats may remain asymptomatic even if infected, it is important to consider the possibility of being an asymptomatic carrier in a multi-cat household and if a cat has D. gatoi problems. These cats can spread Demodex mites to other cats in the household, even if they do not show signs of skin disease.

Causes of Demodectic Scabies in Cats

These three types of Demodex can cause demodectic mange. mite causes:

  • Demodex gatoi . This type is usually seen in healthy cats. They live in the upper layer of the skin and are contagious to other cats.
  • Demodex cat . These mites are usually seen in cats with a suppressed immune system due to an underlying disease or condition. They can be found in hair follicles and sometimes in the ear canals of affected cats.
  • A rare and unnamed Demodex Type. This is Demodex type is very rare, but has been associated with the underlying disease. These mites can also be found in hair follicles.

Diagnosing Demodectic Scabies in Cats

Diagnosing demodectic mange in cats typically requires a test known as a skin scraping. In this test, your veterinarian will use a scalpel blade to scrape off some of the outer layers of skin cells and remove Demodex mites that can live on the skin surface or in hair follicles. Samples obtained through skin scraping will be examined under a microscope to assess the presence of Demodex mites.

Other tests that may be used to assess the presence of Demodex mites include a tape preparation, in which a piece of clear tape is applied to your cat’s skin to remove any parasites that may live on the surface. This piece of tape is then examined under the microscope for the presence of Demodex mites. Plucking samples can also be examined under a microscope to look for Demodex mites that may be present within the hair follicle. Less frequently, more invasive tests such as a skin biopsy may be required to visualize Demodex mites within the hair follicle. Ear infections caused by Demodex mites can be discovered when using a microscope to examine debris from the mite ear canal.

Because Demodex can be difficult to find using the tests above, your veterinarian may suggest a trial of a drug such as fluralaner derivatives that will kill the parasite.

Demodex Gatoi

demodex gatoi, It can be diagnosed using skin scrapings or tape to collect skin and debris that can be examined under a microscope. Stool testing may also be helpful to look for mites or eggs. However Demodex gatoi It can be extremely difficult to find. If your veterinarian suspects an infection but can’t find the real mites, he may recommend continuing treatment. A positive response to treatment confirms the diagnosis.

Demodex cat

Demodex cati it is usually easy to find on deep skin scrapings, which are examined using a microscope. The mites can also be found on ear sticks examined under a microscope.

With Demodex cati cats often have underlying diseases that suppress the immune system. This includes feline viral diseases (FeLV, FIV), cancer, diabetes or toxoplasmosis. In these cases, your veterinarian should perform further diagnostics to identify an underlying cause.

Treatment of Demodectic Scabies in Cats

All Demodex mite species should respond to the same treatments. in cats Demodex Products that are generally effective for treatment include weekly baths or at least two applications of Bravecto® or Revolution Plus® for several weeks. No product, Demodex in cats It is not specifically licensed for the treatment of fleas, but some flea remedies are also effective.

Treatment of feline demodicosis depends on which particular strain of Demodex is involved.

Successful treatment with D.cati depends on identifying the underlying cause of the immunosuppression. While not all infected cats have a suppressed immune system, many cats do. When immunosuppression is addressed or ruled out, antibiotics are given to address secondary bacterial skin infections and medication is given to kill Demodex mites. D.cati treatment options; mites include topical treatments (lime sulfur dips), oral medications such as ivermectin or milbemycin, as well as other newer topical medication options. Each treatment has its own benefits and side effects, so your veterinarian will work with you to determine the best treatment for your cat.
