Diagnosing mange in cats typically involves the following steps:
-
Physical Examination
A veterinarian will first conduct a thorough physical examination of the cat. They will look for signs such as hair loss, itching, redness, and skin lesions, which could indicate mange.
-
Skin Scraping
The vet may take a skin scraping from the affected area. This involves gently scraping the skin's surface with a scalpel blade to collect samples. The samples are then examined under a microscope to look for mites, their eggs, or fecal matter.
-
Tape Test
In some cases, a piece of clear tape may be pressed against the skin to collect mites or eggs for microscopic examination.
-
Fecal Examination
A fecal exam may be performed to check for the presence of mite eggs or larvae.
-
Blood Tests
Blood work may be recommended to rule out underlying health problems, especially if demodectic mange is suspected.
-
Medication Trial
If mites are not detected but mange is still suspected, a therapeutic trial of anti-parasitic medication may be recommended. If the symptoms improve, it is likely that mites were the cause.
-
Differential Diagnosis
The vet will also consider other possible causes of the cat's symptoms, such as flea allergy dermatitis, skin infections, and ringworm, to ensure an accurate diagnosis.
