Understanding Demodectic Mange
Demodectic mange, also known as demodicosis, is a skin condition in cats that is caused by an overgrowth of Demodex mites. These mites are a genus of microscopic parasites that are commonly found in the hair follicles and oil glands of mammals, including humans and cats Cleveland Clinic. While Demodex mites are generally harmless and present in most cats, they can cause issues when their population multiplies excessively.
Demodex Mites Overview
There are two types of Demodex mites that typically affect cats: Demodex folliculorum and Demodex brevis WebMD. These mites have elongated, semi-transparent bodies with eight legs and primarily reside in the hair follicles and oil glands on the face, neck, or chest. They feed on skin cells, oil, and hormones present in these areas.
While the presence of Demodex mites is common, the development of demodicosis is relatively rare in cats Cleveland Clinic. Demodicosis occurs when the mite population multiplies uncontrollably, often due to a poorly functioning immune system. Cats with weakened immune systems, such as those with underlying health conditions or stress, are more susceptible to the overgrowth of Demodex mites.
Causes of Demodicosis
The exact cause of demodicosis in cats is still not fully understood. However, it is believed that a combination of factors, including genetics and immune system function, plays a role in the development of this condition Cleveland Clinic. Cats with compromised immune systems are more likely to experience an overgrowth of Demodex mites, leading to demodicosis.
It’s important to note that demodicosis in cats is not contagious to humans or other animals. The mites that cause demodicosis in cats are specific to feline species and do not pose a risk to human health. However, it is still crucial to provide appropriate treatment and care for affected cats to alleviate their discomfort and prevent secondary skin infections.
Understanding the basics of demodectic mange and the role of Demodex mites in causing demodicosis is vital for cat owners. In the following sections, we will explore the different types of Demodex mites, the symptoms of demodicosis in cats, and the diagnosis and treatment options available for this condition.
Demodectic Mange in Cats
Demodectic mange, also known as demodicosis, can affect cats, and it is caused by two species of mites: Demodex cati and Demodex gatoi. D. cati is typically found within hair follicles, while D. gatoi is more likely to live on the skin surface. Cats of all breeds and ages can be affected by these mites.
Types of Demodex Mites
There are two types of Demodex mites that can infest cats: Demodex cati and Demodex gatoi.
- Demodex cati: This species of mites is commonly found within the hair follicles of cats. Infestation with D. cati can lead to symptoms such as hair loss, skin inflammation, and crusting (VCA Hospitals).
- Demodex gatoi: Unlike D. cati, D. gatoi mites reside on the surface of the skin. Infestation with D. gatoi causes severe itching, inflammation, and crusts along the trunk and limbs of the affected cat.
Symptoms in Cats
The clinical signs of demodicosis in cats can vary depending on the species of mite involved.
- Demodex cati: Cats infested with D. cati may experience hair loss, particularly around the head, neck, and ears. They may also develop skin inflammation and crusting in the affected areas. In some cases, secondary bacterial infections may occur due to the compromised skin barrier (VCA Hospitals).
- Demodex gatoi: Cats infested with D. gatoi typically exhibit intense itching, leading to self-trauma and hair loss. The itching and inflammation are often localized to the trunk and limbs, and crusts may develop as a result of the cat’s excessive scratching and grooming (VCA Hospitals).
If you suspect that your cat may have demodicosis, it is important to consult with a veterinarian for a proper diagnosis and appropriate treatment. Diagnostic methods may include skin scraping tests, acetate tape preparations, or hair pluck samples. Less commonly, more invasive tests like skin biopsy may be needed to confirm the presence of Demodex mites (VCA Hospitals).
To effectively manage demodectic mange in cats, treatment options such as medications like fluralaner (Bravecto®) or sarolaner (Revolution Plus®) may be prescribed by your veterinarian. The choice of treatment will depend on the severity of the infestation and the specific mite species involved.

Diagnosis and Testing
When it comes to diagnosing demodectic mange in cats, several diagnostic methods can be employed. These tests are essential for identifying the presence of demodex mites and confirming the condition of demodicosis. The two primary diagnostic steps are skin scraping examination and additional diagnostic steps.
Skin Scraping Examination
A skin scraping examination is a common diagnostic procedure used to detect demodex mites in cats. During this procedure, a small sample of skin is scraped from the affected area using a sterile blade or scalpel. The collected sample is then examined under a microscope to identify the presence of mites. Skin scrapings can be taken from multiple areas to increase the chances of finding mites, as they may not be evenly distributed across the skin.
Additional Diagnostic Steps
In some cases, additional diagnostic steps may be necessary to confirm the diagnosis of demodicosis in cats. These steps may include:
-
Acetate Tape Preparation: This method involves applying a clear adhesive tape to the affected area and then gently removing it. The tape is then examined under a microscope to identify the presence of mites.
-
Hair Pluck Samples: Hair pluck samples involve removing several hairs from the affected area using forceps. These hairs are then examined under a microscope to check for the presence of mites (Merck Veterinary Manual).
-
Skin Biopsy: In more challenging cases or when other diagnostic methods fail to provide conclusive results, a skin biopsy may be performed. This involves the removal of a small piece of skin tissue for examination under a microscope. A skin biopsy allows for a more detailed analysis of the skin layers and can help identify the presence of mites within the hair follicles.
It’s important to note that a veterinarian should conduct these diagnostic procedures to ensure accurate results. By identifying the presence of demodex mites through skin scraping examination and other diagnostic steps, appropriate treatment options can be pursued to manage demodectic mange in cats. For more information on treatment options, please refer to the section on Treating Demodectic Mange.
Treating Demodectic Mange
When it comes to treating demodectic mange in cats, there are several treatment options available. The choice of treatment depends on the severity of the infestation and the recommendation of a veterinarian. Two common treatment methods for demodectic mange in cats are lime sulfur dips and medications.
Lime Sulfur Dips
Lime sulfur dips are a commonly used treatment for demodectic mange in cats. This treatment involves applying a 2% lime sulfur solution to the affected areas of the cat’s skin. Lime sulfur has acaricidal properties, meaning it can kill mites like Demodex, thereby helping to control the infestation.
Typically, lime sulfur dips are administered once weekly for a period of four to five weeks (Merck Veterinary Manual). This treatment regimen is considered safe and effective, and cats infested with Demodex mites often respond well to it. However, it’s important to follow the instructions provided by the veterinarian and take precautions to prevent the cat from ingesting the solution.
Medications for Treatment
In some cases, medications may be prescribed to treat demodectic mange in cats. These medications typically come in the form of creams, gels, lotions, or washes that contain acaricides, which are pesticides that kill ticks and mites (Cleveland Clinic). The specific medication and application method will be determined by the veterinarian based on the individual cat’s condition.
Some common medications used for treating demodectic mange in cats include Bravecto® and Revolution Plus® (PetMD). These medications work to eliminate the mites and control the infestation. It’s important to administer medications as directed by the veterinarian and to follow up with any recommended follow-up treatments or check-ups.
It’s worth noting that any cats in close contact with an affected cat should also be treated, as Demodex gatoi, one of the types of Demodex mites, is contagious to other cats. Treating all cats in the household helps prevent the spread of the mites and ensures effective management of the infestation.
By following the recommended treatment methods, whether it’s using lime sulfur dips or medications, cat owners can effectively treat demodectic mange and provide relief to their feline companions. It’s essential to consult with a veterinarian for an accurate diagnosis and guidance on the most suitable treatment approach for your cat’s specific condition.
Managing Demodex Mites
When it comes to managing demodex mites in cats, understanding their contagiousness and implementing appropriate treatment measures are crucial for the well-being of your feline companion.
Contagiousness in Cats
It’s important to note that demodex mites are species-specific, meaning they can only survive on one host species. Infected dogs cannot transmit demodex mites to cats, and vice versa. Additionally, these mites do not spread between cats, dogs, and humans. Therefore, if your cat has demodex mites, you don’t have to worry about them being contagious to other pets or family members.
However, there is one exception. If your cat is infected with D. gatoi, a specific species of demodex mite, it can be contagious to other cats in the household. In such cases, it’s important to treat all cats in the household to prevent the spread of the mites. Treatment for D. gatoi is similar to that for D. cati, but clearing up a D. gatoi infestation can be more challenging.
Treatment for Household Cats
When managing demodex mites in cats, treatment options may vary depending on the severity of the infestation. The primary goal is to eliminate the mites and alleviate the symptoms associated with the condition.
Treatment for demodectic mange in cats often involves the use of topical medications, such as lime sulfur dips or medicated shampoos. Lime sulfur dips, containing the active ingredient calcium polysulfide, are effective in killing the mites and reducing skin inflammation. Medicated shampoos specifically formulated to target demodex mites can also be used to help manage the infestation. It’s important to follow the instructions provided by your veterinarian and ensure that the treatment is applied as directed.
In some cases, additional medications, such as antiparasitic drugs, may be prescribed to manage the infestation. These medications work systemically, targeting the mites throughout the cat’s body. Your veterinarian will determine the most appropriate treatment plan based on your cat’s specific condition.
While managing demodex mites, it’s crucial to maintain good overall hygiene and cleanliness for your cat. Regularly wash their bedding, toys, and other items that come into contact with their skin. Additionally, follow any additional recommendations provided by your veterinarian, such as cleaning and disinfecting the environment to minimize the chances of reinfestation.
If you suspect that your cat may have demodex mites, it’s important to seek veterinary attention for an accurate diagnosis and appropriate treatment. Your veterinarian will guide you through the management process and provide you with the necessary tools to help your cat recover from the infestation.
