Common causes of hair loss in cats

Ringworm is one of the most feared diseases associated with cats. It is caused by a fungus, usually Microsporum canis , that feeds on keratin, a protein that forms the outermost layers of the skin. Dogs, rabbits, guinea pigs, and even humans can get it.
It is common in young cats, malnourished or sick adults with weakened or immature immune systems. The clinical picture is variable and depends on the characteristics of the fungus and the cat. In some, there are no symptoms, while others manifest inflammation and a typical lesion consisting of rounded alopecic areas and scaling.

Allergic flea bite dermatitis or DAPP
The DAPP occurs when the cat reacts to components flea saliva . It usually appears for the first time in cats aged three to six years. Symptoms are usually exacerbated in the warmer times of the year when the population of these parasites is highest. Symptoms are often becoming more severe.
The typical involvement is the lumbosacral area, that is, the area at the end of the loin, and the neck, although it can extend to the perineum, abdomen or both sides. This distribution is what helps to guide the diagnosis , since it is not always possible to locate the fleas or their remains.

It is an allergic reaction which appears due to contact with pollens, dust, mold, etc . It is more common in cats under three years of age. The symptoms are variable. We can find alopecia, erosions and, above all, itching.
Respiratory symptoms may also appear, such as coughing, sneezing or breath sounds, and conjunctivitis. Atopy can be diagnosed by excluding other pathologies . It is treated with corticosteroids, drugs to control itching or immunomodulators that affect the immune system.
The triggering allergen can also be sought to develop an immunotherapy, which consists of making a vaccine to gradually desensitize the cat to the component that causes the reaction. In cats, studies are lacking in this regard.
This scabies is caused by a mite called Notoedres cati . It normally affects the head, but can be seen in other locations such as the front legs or the perineal area. It is characterized by intense itching and lesions on the skin, which is thickened, hairless and crusted.

It is diagnosed according to the symptoms and observing the mite under a microscope, in the material of a skin scraping. It is a contagious disease that could be transmitted to people, although in a mild way. It is treated with acaricides.
Dermatitis by malassezia
Malassezia is a yeast that normally lives on the skin and mucous membranes of cats . When an imbalance occurs in these, such as dermatitis or a skin problem, malassezia can proliferate excessively, especially in areas of folds.
This increase in its population causes more or less itching and lesions of greater or lesser severity, which usually lead to alopecia, scaling and redness. There may be a bad odor and, without treatment, the skin eventually thickens and darkens.
By taking a sample, this parasite can be discovered under the microscope. The diagnosis is confirmed if their number is very high and there is a response to treatment. This may consist of baths, ointments, or oral antifungals.
Feline psychogenic alopecia
In this case, the hair loss is caused by the cat itself, which pulls it off in an excess of self-grooming and licking . The skin is appreciated, in principle, healthy. Alopecia occurs in any part of the body that the cat reaches with its mouth.
It is mostly seen on the sides, on the hind limbs, or in the perineal region. The cause of the cat adopting this behavior is stress or anxiety . This condition can be triggered by many different causes, such as changes in your home or family. For example, a move or the arrival of a new member.

Telogen effluvium is another of the processes that are related to stress. When this lasts or is very intense, it can interrupt the normal cycle of the hair . After overcoming this period, what happens is that the formation of the new hair is restarted, at the same time that all the old hair is suddenly eliminated.
This happens between one and three months after the event that triggered the stress. The consequence is a more or less extensive alopecia. Diagnosis is usually reached by ruling out or after examining the cat’s medical history. It is not necessary to prescribe any treatment.
Feline idiopathic symmetric alopecia
A cat with this type of alopecia loses hair symmetrically and in the abdominal area , which includes armpits, belly, perineum and inside of the hind legs. The skin looks healthy and the hairs are not broken, contrary to what happens in psychogenic alopecia.
It is suspected that the origin of this alopecia is in an endocrine alteration. Many of the affected cats can experience improvement with the administration of hormones.
