Demodicosis in cats: symptoms, treatment and prevention

Demodicosis in a cat is caused by a subcutaneous tick. The problem can affect all animals, regardless of breed or age. However, it should be understood that this tick is constantly on the pet's skin, but the disease occurs due to a weakened immune system, against the background of constant chronic pathologies and other negative factors. Veterinarians recognize the tick as opportunistic because only a failure in the immune system leads to the manifestation of the clinical picture of the disease.

Causes of the problem

The skin of most animals is often parasitized by the Demodex mite, while it does not cause problems and does not bother the pet.

  • presence of worms and intoxication caused by their vital activity;
  • insufficient dietary fat intake;
  • immunity weakened by frequent illnesses;
  • lack of vitamins A, E and group B;
  • wrong conditions of detention (dampness, dirt);

How the disease progresses

Depending on the degree of damage and the development of the problem, the following forms of the disease are distinguished:

  1. Localized. Demodicosis in a cat manifests itself in a certain area. It usually affects the mouth, eyes, ears, or neck. If treatment is started on time, the prognosis is always favorable.
  2. Generalized. If you ignore individual areas of the lesion, then soon the tick will affect multiple zones. Demodicosis can develop rapidly in individuals that are predisposed to this pathology. Therefore, veterinarians recommend neutering or spaying the animal after the course of treatment in order to stop the appearance of kittens with hereditary vulnerability.

Typical signs of the manifestation of the disease

It is worth noting that the first signs of the disease are difficult to notice immediately. Pathology develops slowly, which is why the owner of the pet does not notice the areas affected by demodicosis for a very long time. Every cat owner should know the symptoms and treatment of a cat.

Signs to watch out for:

  • wool loses its former luster, becomes dull and lifeless;
  • may appearreceding hairline;
