Some Common Cat Skin Diseases

Some Common Cat Skin Diseases

Cat skin diseases mainly include:

1) Bacterial skin disease: mainly caused by bacterial infection;

2) Fungal skin disease: it is caused by dermatophyte infection; dermatophytes can survive for more than one year in a dry environment, they have strong resistance. Some fungi also have affinity for the soil and can grow and reproduce in the soil and have a long-term survival.

3) Ectoparasitic dermatosis: caused by fleas, warts, demodex, ear mites, lice, tick, etc.;

4) Metabolic skin disease: such as hormonal skin disorders and allergic dermatitises;

5) Abnormal immune skin disease: such as nutrition-related skin diseases.

Among all these diseases, fungal skin diseases accounted for more than 80% of cases, and pathogenic cats’ fungal skin diseases were caused by canine microsporosis, which dogs, cats and humans can all be infected with. Dermatologists often misdiagnose that as allergic dermatitis caused by cat hair, which has led many owners to abandon their cats.

Fungal skin disease

The main transmission route of dermatophytes is contagious infection. It can be transmitted through the cat’s contaminants and contaminated combs, brushes, and bedding. The disease can occur throughout the year, with a high morbidity in hot and humid weather. Cats cured after fungal disease are resistant to re-infection of the same disease, but the resistance will disappear within a few months to a year. The fungus can infect humans and animals, and children and women are more susceptible to.


After the infection of the cat’s skin with fungus, it often occurs in the head, ears, limbs, claws and the trunk. The skin of the affected area was depilated, a ring-shaped scaly spot appeared, and the damaged hair roots remained. Sometimes the affected area was completely depilated. Severe cases will occur erythema or crusts.  

The affected area was itchy. Some cats will scratch it and cause secondary bacterial infections, which will lead to severe exudation and redness and even fester of the affected area. The development of skin fungus disease generally spreads from the middle to the periphery. If it is not treated promptly, it will become a chronic course of disease.

Take your cat to the veterinary for a check-up if the above symptoms occurred.
