Categorizing Skin Allergies In Cat
The immune system releases a protein known as IgE as the allergens react with the cat’s skin or get into the cat’s body.

The skin allergies in a cat are broadly classified as follows
- Inhalant/ Contact Allergies
- Food Allergy
Flea Allergy Dermatitis
This is an allergy which is caused because of the sensitivity towards the flea’s saliva. As these blood-sucking fleas bite the cats they tend to spit their saliva. This saliva causes the allergy in the cats.
Also, this allergy leads to certain secondary infections too.
- Serious itches
- Hot spots over face and hips
- Biting or chewing the tail and legs
- Lesions, oozing due to chewing
- Serious damage in the skin due to scratches

Appearance Of Cat Skin Allergies
There are various types of feline skin allergies that affect the cats. Due to this a vet tries to diagnose the cat’s skin by analyzing the condition categorized in about 4 different patterns.
Though the pattern is not used to determine a specific diagnosis it would help in understanding the type of skin disease or the condition which is troubling the cat.
Cat Military Dermatitis (Papulcrustous Dermatitis)
It is a skin allergy which is usually seen in the cat’s back however it may also affect any other body part of the cat. It is generally accompanied by few other cat skin infections such as allergy to flea bites.
Feline symmetrical alopecia
This skin allergy causes spotty patterns along the short stubby hair in the cat. The cat tends to lick its hair which appears as though the cat’s hair is falling all over.
It is a condition that generally appears on the belly of the cat, rear legs and side parts of the lower abdomen. This condition generally doesn’t affect the back of the cat.
Eosinophilic granuloma complex
There are certain reasons which could cause this condition which includes:
- A slow growth of ulcer (indolent)
- Eosinophilic plaque: highly defined, increased, ulcerated and severely itchy (pruritic) lesions which appear on the cat’s skin generally abdomen or hind legs.
It is a collective term titled for the lesions( infected patch of skin) of eosinophilic ulcer ( a cut on the lip of the cat), eosinophilic plaque (lesions that appear on the skin generally over the abdomen or hind legs) and linear granuloma (tiny nodules on the skin).
This is generally due to the allergic infection caused by some element in the cat’s surrounding, fleas, and diet.
Head and neck pruritus (inches)
This is an allergic reaction which leads to itches in the lead and neck areas of the cat. There is a tendency of hair loss and severe skin damage which is caused because of the itching.
Breakages in skin and cheeks may also appear. However, the vets consider that this is caused due to an infection by the herpes virus after being administered a vaccine to the cat.
There is a difference in the concept of food allergies and food intolerance. Food allergies are generally accompanied by certain signs like itchiness and skin issues. But, food intolerance has signs of vomit sensation and diarrhea.
According to researches fish, dairy items and beef are the usual offenders in this type. Even though most of the proteins are the same, there are certain types of proteins that are antigenic compared to others.
Allergic reactions could be determined based on the quantity of protein being exposed to.
- Skin itchiness
- Military dermatitis
- Loss of hair
- Skin scratching
The food allergy symptoms are not specific to any period it is seen almost throughout the year. However, it develops much during the winter which is not in the case of other allergies.
- If the condition is diagnosed correctly, treating it quite easy and simple. You may choose a specific cat food available for this purpose or draft a diet plan on your own for the cat.
- If you are planning a diet on your own, you can try the elimination technique by cutting down the food items slowly one after the other to conclude with the allergic food the “the culprit’.
- For example, you can try a vegetable diet and chicken diet for about a week or two and check for any allergic symptoms. If not, try beef for another two weeks and see if there is any change.
- If the cat seems to develop allergic reactions to pork then avoid pork from the cat’s food and understand that your cat is allergic to pork.
- Make sure to prepare a properly balanced diet for the cat which has a correct proportion of vitamins and minerals.
Generally, people don’t consider allergies as a serious problem which is a big blunder. Though allergies may not be fatal on its own, the complexities it may cause in the health may end up fatal.
Considering its serious side effects it is important to take adequate care of the pet for its healthy life.
