1) Allergies
Allergies of environmental origin (dust mites, pollens, fleas) or food can be the root cause of hair loss. Low-end food can, for example, cause allergies in animals.
DAPP or dermatitis, an allergy caused by flea bites, is a real risk factor for hair loss. Intolerance can result in attacks of scratching and licking in the rump or thighs.
2) ringworm
Ringworm is a common pathology in cats. Very resistant, the risks of contagion in humans are also high. It is a microscopic fungus that feeds on the keratin in the hair of these felines and manifests itself in hair loss, which tends to spread throughout the coat.
When the hairs fall out, they give way to more or less red and scaly hairless areas, most often circular. Ringworm usually appears on the thighs, back and head of the cat. Since cats infected with ringworm show no visible symptoms, this increases the risk of infection in humans and other pets.
3) scabies
In cats, mange is a skin infection of microscopic mites. It is often found on the ears and on the head of the feline and rarely spreads on the body. This disease is manifested by intense itching. These cause injuries caused by scratching, scabs, and hair loss. This disease can be found in young cats and kittens but is rare.
