Cats’ allergies are a surprisingly frequent phenomenon. Cats’ allergic reactions may be either food-based or non-food-based.

Non-food allergies may be caused by bites of various insects like mosquitoes or fleas, and also caused by snake bites. Such allergic reactions are typical for cats living in country houses or walking by themselves. Food-based allergies may appear as negative reactions to some ingredients of the nutrition or as allergic reactions to the nutrition in general and/or to food supplements.

Special cat nutrition may also cause allergic reactions, which appear in the form of gastric indigestion or gastric disturbance. Systematic consuming of dry food or special pates will also very likely cause such symptoms. If you notice that your pet develops such symptoms, it is better to begin feeding it with natural homemade food. Furthermore, you may find out that when your cat sometimes eats the food from your bowl, other cats’ food or scraps, all these factors don’t lead to such deleterious symptoms.

Sometimes cats may develop an eosinophilic granuloma. Usually this notion means an ulcer, which is localized on the mucous membranes of the lips. That usually happens to young cats. In practice, it is reasonable to name such conditions as an eosinophilic ulcer. An eosinophilic ulcer is a special case of an eosinophilic allergic syndrome. Frequently cats’ allergies are evident in the form of this syndrome. 

An eosinophilic allergic syndrome also manifests itself as an eosinophilic pracula, an eosinophilic ulcer, an eosinophilic granuloma and allergic military dermatitis.

Allergic reactions may appear with various effects simultaneously.

Among specific symptoms of allergy are reddening, the formation of blisters, and frequent scratching. Allergic reactions can be easiest noticed at the paws and the neb or the tail. The evidence of growing symptoms are scratching of a cat’s body till it bleeds or soft tissues edema.

An Ulcer

Ulcers are usually localized on mucous membranes, in the mouth cavity or on skin. Such affects are often determined by immunological responses. There is no special susceptibility depending on the breed or the age category. 

The upper lip is often affected from one side; sometimes it can be two-sided. An ulcer has a clear dividing line, it is reddish-brown, and the size can vary from 2 mm to 5 cm. Sometimes an ulcer can appear together with pain or itching, but such cases are rare. An eosinophilic ulcer should be distinguished from symptoms caused by different traumas, infection processes or new growths.

An Eosinophilic Pracula

It is the most common evidence of an eosinophilic allergic syndrome. There is no special susceptibility depending on the breed or the age category. An eosinophilic pracula is often localized in the abdominal region or in the medial surface of the upper legs. Affections can be either singular or plural. There can be oval, pitched, and erythematic (red).

The affections have a sharp contour. They may effuse exudation (liquid). An ulceration may develop. The size of the affections varies from 5 to 50 mm. They should me differentiated from granulomas caused by an infection or new growths.

Allergic Miliary Dermatitis

Such disease can be caused by various factors.In most cases this pathology is caused by allergic skin reactions. It can also be caused by outside environment allergens and external culprits like, for example, fleas or by various medicaments. The age and the breed of an animal don’t have an impact on the development of the pathology. During flare-ups, multiple rashes in the form of pimples can be noticed. The pimples have tightly adjoined barks. Such barks are known as initial skin elements. They don’t appear because of self-traumatization. They are usually localized on the back, on the posterior surfaces of the upper legs and on the neck of an animal. The itch can be either moderate or intense. In inveterate affections pigment spots can be noticed. The issue can also be cause by non-allergic reasons, for example, by staphylococcal folliculitis, dermatomycosis or pemphigus foliaceus, so differential diagnostic procedures are required.

An Eosinophilic Granuloma

An eosinophilic granuloma is considered to be the unmasking of allergy. It can be found on the skin, mucous membranes, in the mouth cavity, and mucocutaneous tissue. The age and the breed of an animal don’t affect the development of the pathology. The affection can be localized on any part of an animal’s body, but more often they appear on the neb or on the back surface of the upper legs. The symptoms include linear plaques of yellowish-pink color, which have a clear dividing line. 

An eosinophilic granuloma often causes painless swelling of the lower lip and edema which is localized around the chin. It may also cause a moderate itch. An eosinophilic granuloma should be differentiated from infectious granulomas and new growths.

Eosinophilic Allergic Syndrome Examination

The veterinary center dermatologist recommends examining a cat if the animal develops any of the symptoms mentioned above.

First you should define whether there is an ectoparasitic invasion. This can be done by a checkup, a humid paper test, a skin surface scrape to reveal different parasites like mites or lice and others. But it is better to provide the treatment against parasites even in the cases when the tests are negative. Then you should give your pet a trial feeding. It is recommended to begin a month after the empirical treatment against parasites. The diet is recommended to be composed of unusual sources of proteins. Both natural homemade food and dried nutrition can be used. Such an exclusive diet should be followed for eight months at least.

Also, you should do allergy testing. In these cases, such testing is used as the next step in diagnostics. 

        Allergy Tests may reveal the allergens, which cause cats’ allergy. Such allergens can be dust, dust mites, blossom dust, mold fungi and many others. If some medicines were used before the affection, they should be discontinued as they may appear to be the reason of the allergic reactions.

The Treatment

In general, it is better not to start the treatment until after doing antiparasitic control. But if the symptoms are uncomfortable for your animal, you can combine the treatment and antiparasitic medicines. Anti-inflammatory medicines can be used like, for example, dexamethasone or prednisolone. When the symptoms are improved, you should lessen the dose of the medicines and continue the therapy. Then in some period of time the medicines should be discontinued. Immunosuppressants can also be used like, for example, cyclosporine A. Such medicines are used in case the steroids don’t produce any effect. If the allergy was caused by natural environment allergens, desensitizing vaccines can be used.

Also, cats may have allergic rhinitis. When they sneeze, the nasal discharge is watery.

As with people, cats may be allergic to dust or blossom dust. The treatment in such cases consists of defining the allergens, limiting the cat’s contact with them and applying medical treatment.All that is mentioned above shouldn’t make you conclude that you should indulge your cat. It is better for you to try to understand the cat’s behavior, reactions, and try to control them in time.

In conclusion, we must mention the unpleasant character of many allergens to be accumulated in an animal’s body. Above the critical threshold or in any other situations, the reaction is immediate.
