How to judge whether a cat has fungal skin disease?

In daily life, most cats suffer from fungal skin diseases because of improper care by their owners. Many owners often just blow-dry the cat's fur by 90% or just blow-dry it after taking a shower, and then let it dry naturally, which provides a good living environment for fungi, thus causing fungal skin diseases.

The disease is mainly diagnosed in the laboratory. It is the most inaccurate and irresponsible practice to make empirical diagnosis with naked eyes, which should be recognized by both the owner and the veterinarian.

1. Check with a Wood lamp or fluorescent lamp that can generate ultraviolet rays with a wavelength of 3660A. Put the sick cat in a dark room and illuminate the affected part with Wood's lamp. If it is a fungus infected by microsporum canis, the affected part can emit yellow-green fluorescence, which is the diagnosis. If infected by other fungi, there is no fluorescence. Dandruff, vaseline and some ointments all show green fluorescence and should be excluded, with a detection rate of about 50%.

2. Pathogenic bacteria examination: scrape the fur or dander on the edge of the affected skin on the glass slide, add a few drops of 10% potassium hydroxide to the quilt, heat it slightly on the alcohol lamp, press the cover glass, and observe it under the microscope.
