Diagnosis: A skin scraping exam uses a scalpel bract to gently scrape along the surface of the skin to look for the presence of mites or mite eggs.

Treatment: Dips, Ivermectin injections, or Revolution topical treatment. It may be necessary to prune long-haired cats earlier treatment to heighten penetration.

Demodicosis

Demodicosis is an inflammatory skin disease in cats caused past the Demodex mite. There are two species, Demodex cati and Demodex gatoi, both of which can infect cats.

• Itching

Diagnosis: Skin scrapings and swabs from the ears, which are examined under a microscope to look for the presence of mites.

Treatment:

Lime sulfur dips to impale the mite. Other treatments include Amitraz; however, information technology is quite toxic to cats, and then great care is essential. Treat all cats in the household.

Sarcoptic mange

This type of mange is far more common in dogs than it is in cats. Caused by the parasitic mite Sarcoptes scabei, this mite about oft affects kittens and cats living with dogs. The parasite is highly infectious and can live for several days off the host.

Diagnosis: Woods'due south lamp exam, skin scrapings, fungal civilization, examination of hairs to await for the presence of fungal spores and fungal PCR.

Treatment: Anti-fungal medications such as Itraconazole and Griseofulvin or lime sulfur shampoos and dips.

Insect seize with teeth

Some cats can develop hypersensitivity to insect bites, mosquitoes are the most common culprit, merely any bitter or stinging insect can produce a hypersensitivity. As your cat scratches, the ear can get farther damaged, exposing the underlying layers to bacteria.

Squamous cell carcinoma

Squamous jail cell carcinoma is a cancerous tumour of the skin, and 1 of the most common causes is backlog exposure to the sun. Tumours can develop on any part of the torso, just the ears, olfactory organ, mouth, and eyelids are the well-nigh common locations.

Symptoms:

• Cherry-red and crusted sores
• Bleeding ulcers that don't heal
• Dried areas of skin effectually the growth
• Pilus loss in the affected area

Diagnosis: A presumptive diagnosis is often fabricated during the concrete examination; this will be confirmed by biopsy.

Allergy

Several allergies can develop in cats with a broad range of symptoms. The virtually common are:

• Insect – The most common insect allergy is due to flea bites. Cats can develop an allergy to any insect seize with teeth, the near mutual (aside from fleas) is the mosquito.

In that location are iii types of pemphigus in cats ranging in severity.

Symptoms:

• Small ruddy spots, hair loss, and blister-similar vesicles which eventually break open and class thick, yellow crusts. The status starts around the eyes and olfactory organ before spreading to the ears, face and other parts of the body
• Afflicted areas are itchy and painful
• Secondary bacterial infection may also develop

Diagnosis: Punch biopsy, direct immunofluorescence to look for antibodies, and cytological exam of an intact pustule.

Handling: Immunosuppressive therapy which may include topical corticosteroids for mild cases or oral corticosteroids for moderate to severe cases. The veterinarian will prescribe a high dose until remission is achieved, and the cat will then be tapered to a maintenance dose.

Systemic lupus erythematosus

• Oral and nasal ulcers
• Paronychia, inflammation around the claw beds

Diagnosis:  SLE requires multiple tests, which may vary depending on the organisation affected.

• Routine tests including biochemical profile, complete blood count, and urinalysis
• Coombs test to detect the presence of antibodies in the blood
• Antinuclear exam which measures antibodies to cocky-tissue
• Biopsy of a skin lesion

Treatment: There is no cure for SLE; the goal of treatment is to relieve symptoms, which can include oral and/or topical corticosteroids to reduce inflammation and itching and limit exposure to sunlight.

Frostbite

A cat'due south ears are decumbent to frostbite if they accept access to outdoors in cold temperatures equally they have piffling fur to protect them from the elements. As the temperatures drop, blood menstruation diverts from the extremities (including the ears) to preserve cadre temperature (and protect vital organs such every bit the heart and kidneys). Dampness can exacerbate the trouble. Commencement-degree frostbite affects the epidermis (outermost layer of the skin), second-caste frostbite affects the epidermis and the dermis, third-degree frostbite affects the epidermis, dermis, and the underlying tissue.
