Common domestic cat diseases and treatment options

  1. Cat moss

Cat moss is a minor disease, but the trouble is that it will recur repeatedly, especially in families with multiple cats, and it is basically impossible to escape this disease. Cat moss is a common skin disease in cats, which is simply a fungal infection. For cats with relatively small months, generally poor physiques are more likely to get cat moss, such as a small milk cat that has just been bought home, because its own resistance is not enough and the environment is changed, it is easy to be infected with cat moss. The other is because the living environment is warm and humid, which leads to fungal infection.

  • Symptoms of cat moss

There are 2 species of fungi that infect cats, namely, Microsporum canis and Trichophyton mentagrophytes, 98% of which are Microsporum canis. The most common locations are the ears and chin (where the cat scratches more), and as the disease becomes severe, it may spread to the whole body. In the early stage, there will be small areas of moss spots, the hair will fall off, and there will be dry dander on the surface; because cat moss will be very itchy, the cat will not be able to resist rubbing, so it is easy to spread to other parts of the body. As the fungal infection worsens, skin ulcers, large areas of alopecia areata, etc. may appear. For pet owners, if there is a wound on the body and the cat comes into contact with it, it is easy to become infected. But don’t worry, the symptoms of human infection are also small areas of dry skin, peeling, itching, etc., just apply the ointment in time and pay attention to cleaning, generally it will not have much effect.

How to determine cat moss?

Use the “black light” method to confirm whether your cat is diagnosed with cat moss.

The black light, also called Wood’s lamp, was invented by Robert W. Wood and is known as the skin microscope. The black light can emit ultraviolet rays with a wavelength of 320nm~400nm, irradiate on the skin, pass through the stratum corneum, and reach the dermis layer, activate the fluorescent substances in the skin, such as melanin and dermal colloid, so that the skin emits uniform and dim blue-white fluorescence .

Once the skin is abnormal, such as vitiligo, the melanocytes cannot secrete melanin normally, and bright blue-white areas will appear under the illumination of black light. For example, Microsporum canis, which causes cat moss, produces a fluorescent substance, pterin, in the process of metabolism. This substance emits blue-green light when exposed to ultraviolet light.
