What is Feline Miliary Dermatitis?

Miliar dermatitis is a common sign in many conditions . To be able to compare, it is tantamount to saying that a person has a cough. The origin of the cough can be quite varied and may even have nothing to do with the respiratory system, and so does feline miliary dermatitis.

The terms “miliary dermatitis” refer to the appearance on the cat’s skin of a variable number of pustules and crusts . In other words, it is a rash, especially in the head, neck and back, but it is also quite frequent in the abdomen and we can observe it when shaving the area.

In general, many appear and are small, which is why the word “miliar” is used. Although we have not noticed (because the cat lives abroad), it is almost always accompanied by itching, which in fact is directly responsible for this eruption.

The most common causes of miliar dermatitis are:

  • Parasites (ear mites, notodroid mange mites, lice, …).
  • Allergic dermatitis to flea bite.
  • Atopic dermatitis (can be defined as a generalized allergy, from dust mite to pollen, passing through various types of materials).
  • Food allergies (allergy to some feed component).

External parasites as cause

The most common is that our cat has some parasite that causes him itch , and the constant scratching originates the eruption that we know as miliar dermatitis. The following are the most common ones:

  • Ear Mites ( Otodectes cynotis ): This small mite inhabits the cats’ ears, causing a major itching with their activity. It usually gives rise to the appearance of miliary dermatitis around the neck and around the auricular pavilion, including the nape of the neck.
  • Mange mite notoédrica ( Notoedres cati ): A mite cousin of sarcoptic mange the dog, but feline version. In the early stages the lesions are usually seen on the ears, skin of the neck, nasal plane … The skin thickens in a considerable way due to the continuous scratching. You can get more information about this disease in the Expert’s article on scabies in cats .
  • Lice : It is very common to see them in colonies of cats. Its sting (feed on blood), causes an itch again that the cat tries to calm if scratching. And from there arises the eruption that we refer to as miliar dermatitis.

Treatment to follow

These external parasites respond to the application of topically (on intact) or systemic (eg, subcutaneous ivermectin) selamectin. Nowadays we find for sale many pipettes that contain selamectin and also optical preparations to apply directly to ivermectin-based ears.

As in almost all acaricidal treatments, it should be repeated after 14 days, and a third dose may even be required. In the case of lice, fipronil applied at the indicated frequency several times is usually quite effective.

Allergy to flea bite as a cause

One of the most frequent allergies, which gives rise to miliar dermatitis , is allergy to flea bite . These parasites inject an anticoagulant so it can suck the cat’s blood and it can be allergic to these parasites.

Even after all fleas are eliminated, this allergen remains present in the body for days, causing itching even though those responsible have been eliminated. In fact a single flea is already used to trigger the process if the cat is allergic, but in the case of more fleas, miliary dermatitis is more serious, almost always.

The treatment of allergy to flea bite as the cause of miliary dermatitis is quite simple, it should just end with fleas. There are effective pipettes that repel the insect before it can feed.

Atopic dermatitis as a cause

It is difficult to define atopy. We refer to it as the process in which the cat is allergic to various things and this generates the inevitable itching, which associated with it appear these crusts and pustules that call it miliar dermatitis.

Treating it is almost more difficult than diagnosing it or defining it, and it is necessary to resort to therapy with corticosteroids and other adjuvant treatments, though not by themselves, as polyunsaturated fatty acids.

Food Allergies as a Cause

You see it more and more often, but maybe it’s because each time we care more about our cats and we notice things that were not repaired before.

Often there is no trace of fleas or parasites, but our cat scratches continuously, causing this miliar dermatitis, which as in previous cases, can become contaminated and lead to a more or less severe infection

It does not have to be always this way, but the itching usually appears in the part of the head and neck and with time, is usually generalized. It is frustrating, since corticosteroid therapy is often tried but does not give the expected result. It may be that it cooks for a few days, but there is no clear improvement. Until you completely eliminate the previous diet the cat did, and if you try to keep it for 4-5 weeks with a hypoallergenic ration and water, exclusively.

In the second week you will notice that the dermatitis miliaris is diminishing, the itching is lighter, and in the fourth, it will practically have disappeared. Reintroduce the previous diet to prove that in two the cat scratches again, is the definitive way to diagnose it, but almost no veterinarian feels it necessary to do so.

There are still many other causes of miliary dermatitis in cats, from superficial skin infections, autoimmune diseases, external parasites beyond those mentioned, etc. But the intent of this article by YourCatCareguide was to emphasize that miliary dermatitis is simply a common symptom of innumerable causes , and until the cause is eliminated, dermatitis will not disappear.

This article is purely informative, in YourCatCareguide.com.br we do not have the capacity to prescribe veterinary treatments nor to make any type of diagnosis. We suggest you bring your pet to the veterinarian in case of any type of condition or malaise.
