What type of cats do not cause allergies
In many cases, the most effective way of managing an allergy is to avoid the allergen that causes the reaction whenever possible.
For example, if you own a food allergy, you should check a food’s ingredients list for allergens before eating it.
There are also several medicines available to help control symptoms of allergic reactions, including:
- decongestants – tablets, capsules, nasal sprays or liquids that can be used as a short-term treatment for a blocked nose
- antihistamines – these can be taken when you notice the symptoms of a reaction, or before being exposed to an allergen, to stop a reaction occurring
- lotions and creams, such as moisturising creams (emollients) – these can reduce skin redness and itchiness
- steroid medicines – sprays, drops, creams, inhalers and tablets that can assist reduce redness and swelling caused by an allergic reaction
For some people with extremely severe allergies, a treatment called immunotherapy may be recommended.
This involves being exposed to the allergen in a controlled way over a number of years so your body gets used to it and does not react to it so severely.
Symptoms of an allergic reaction
Allergic reactions generally happen quickly within a few minutes of exposure to an allergen.
They can cause:
- red, itchy, watery eyes
- a runny or blocked nose
- wheezing and coughing
- a red, itchy rash
- worsening of asthma or eczema symptoms
Most allergic reactions are mild, but occasionally a severe reaction called anaphylaxis or anaphylactic shock can happen.
This is a medical emergency and needs urgent treatment.
Substances that cause allergic reactions are called allergens.
The more common allergens include:
- food – particularly nuts, fruit, shellfish, eggs and cows’ milk
- dust mites
- medicines – including ibuprofen, aspirin and certain antibiotics
- animal dander, tiny flakes of skin or hair
- latex – used to make some gloves and condoms
- mould – these can release little particles into the air that you can breathe in
- insect bites and stings
- grass and tree pollen – an allergy to these is known as hay fever (allergic rhinitis)
- household chemicals – including those in detergents and hair dyes
Most of these allergens are generally harmless to people who are not allergic to them.

What causes allergies?
Allergies occur when the body’s immune system reacts to a specific substance as though it’s harmful.
It’s not clear why this happens, but most people affected own a family history of allergies or own closely related conditions, such as asthma or eczema.
The number of people with allergies is increasing every year.
The reasons for this are not understood, but 1 of the main theories is it’s the result of living in a cleaner, germ-free environment, which reduces the number of germs our immune system has to deal with.
It’s thought this may cause it to overreact when it comes into contact with harmless substances.
Is it an allergy, sensitivity or intolerance?
A reaction produced by the body’s immune system when exposed to a normally harmless substance.
The exaggeration of the normal effects of a substance.
For example, the caffeine in a cup of coffee may cause extreme symptoms, such as palpitations and trembling.
Where a substance causes unpleasant symptoms, such as diarrhoea, but does not involve the immune system.
People with an intolerance to certain foods can typically eat a little quantity without having any problems.

Cats exposed to allergens may develop allergies or allergic reactions.
Allergies tend to become evident and intensify over extended periods of time and can take years to develop. Some allergic diseases and allergies in cats include feline atopic dermatitis, flea allergy dermatitis, feline-mosquito hypersensitivity, and food-induced allergy. In the case of feline atopy, hypersensitivity to allergens is due to genetic predisposition.
However, various allergies may arise due to environmental factors. Allergens, ingested, inhaled, or airborne, can be seasonal or non-seasonal, similar to allergies in humans. Suspected seasonal allergens include but are not limited to pollen, fleas, and mosquito bites; suspected non-seasonal allergens include but are not limited to plastic materials, food, dust, trees, and grass.
After exposure to suspected allergens, symptoms may be immediate or delayed, arising within a few minutes to two hours. Symptoms can include both dermatological and gastrointestinal signs such as itchy skin, hair loss and excessive scratching. In cases of feline atopic dermatitis or atopy in cats, pruritic skin diseases may result; however, signs can also include miliary dermatitis, symmetrical alopecia, and lesions of the eosinophilic granuloma complex.
Food allergies account for approximately 10% of allergies in both dogs and cats. Food allergies are often mistaken for food intolerances, which can result in vomiting and diarrhea instead of dermal issues.
In most cases where food allergies happen, they do so with foods that cats eat most often. Common food allergens in cats include beef, dairy, fish, eggs, and chicken.
Preservatives and other additives are also occasionally involved in triggering an allergic reaction. There is no specific breed or age range that food allergies target; however, there are certain breeds that are more susceptible to food allergies than others. For example, Siamese and Siamese crosses may own a higher risk of food allergies than other breeds.
