Mange in Cats (Demodectic and Sarcoptic)

What It Is:

Mange is a skin disease caused by microscopic mites that burrow into or live on the skin, leading to itching, hair loss, and inflammation. While mange is more common in dogs, cats can develop it too. The two main types of mange in cats are demodectic mange and sarcoptic mange, each caused by a different type of mite.

Mange is uncommon in healthy cats, but it can occur in kittens, stray cats, or those with weakened immune systems.

🐾 Common Symptoms

Symptoms of mange can vary depending on the type of mite and the cat’s immune response, but may include:

  • Intense itching and scratching
  • Patchy hair loss
  • Red, scaly, or crusty skin
  • Thickened or wrinkled skin in chronic cases
  • Sores or scabs from self trauma
  • Ear irritation or discharge
  • Poor coat condition
  • Restlessness or agitation

In severe cases, cats may develop secondary bacterial infections from scratching and skin damage.

🦠 Types of Mange and Causes

Demodectic Mange (Demodicosis):
Caused by Demodex mites, which normally live in small numbers on healthy skin. In some cats, especially those with a weakened immune system, the mites multiply and cause skin disease.

  • Often localized around the face, eyes, or neck
  • May be non itchy or mildly itchy
  • Seen in young cats or those with underlying illness

Sarcoptic Mange (Scabies):
Caused by Sarcoptes scabiei mites, which burrow into the skin and cause intense itching.

  • Highly contagious between animals
  • Causes severe itching, hair loss, and skin damage
  • Rare in cats but may occur from exposure to infected dogs or wildlife

Other less common mites like Notoedres cati and Cheyletiella can also cause mange-like symptoms in cats.

🔍 Diagnosis

Diagnosis involves identifying mites or ruling out other skin diseases.

Veterinary diagnostics may include:

  • Skin scrapings examined under a microscope to find mites
  • Fur plucks or tape tests
  • Fecal exam, as cats may ingest mites while grooming
  • Response to treatment if mites cannot be found
  • Skin biopsy in difficult cases

Because mites are tiny and hard to find, multiple tests may be needed for diagnosis.

💊 Treatment

Treatment depends on the type of mange and severity of symptoms.

Common treatments include:

  • Topical medications such as lime sulfur dips or moxidectin
  • Oral or injectable treatments such as ivermectin or fluralaner
  • Medicated shampoos or skin soothers
  • Antibiotics for secondary infections
  • Anti inflammatories to reduce discomfort
  • Regular cleaning of bedding and environment

In multi cat households, all pets may need treatment or testing. Some mites can survive in the environment, so disinfection is important.

🩺 Prognosis

With proper treatment, the prognosis is excellent:

  • Localized demodectic mange often resolves with minimal treatment
  • Generalized or sarcoptic mange requires a longer treatment course
  • Underlying immune problems may affect recovery
  • Most cats respond well within two to four weeks

Recheck visits help ensure the mites are fully eliminated.

💡 Cat Owner Note

If your cat is scratching like crazy or losing fur in strange patches, it could be more than allergies. It might be mange. While rare, it is uncomfortable and contagious in some forms. The good news is that once identified, mange is treatable and your cat can return to feeling and looking like themselves again.
