Not An Allergen
I have super sensitive skin, with lots of positive reactions on my patch test. This means owning a cat is definitely out of the question, right? Maybe…but maybe not.
Cats do produce allergens, most commonly in their sebaceous glands and saliva (which is then transferred onto its dander during grooming) but these allergens are not common skin contact allergens. More on that below…but for now, suffice it to say that your skin reaction might be due to what your cat comes into contact with that is a common skin allergen, as opposed to what kitty produces.
If you haven’t prick tested positive for cats, you might still react to your furry friend if, for example, she comes into contact with top skin allergens — like fragrances, dyes, and preservatives — in pet shampoos or deodorants, carpet sprays and cleaners, insecticides, or even laundry product residue on your clothing or linens. If your prick or blood test shows you are not allergic to cats but you do have have a history of skin sensitivity, care for kitty with hypoallergenic products and keep a hypoallergenic household without your particular skin allergens.
Food and pet allergies function differently (type B cells) from skin allergies (type T cells are involved). A skin prick test will show you if you are allergic to your cat’s saliva, sebum, or other allergens, and a skin patch test tells you if you can come into contact with cats. But prick tests can be imperfect, and epicutaneous patch tests can sometimes miss protein dermatitis. If your prick test shows a sensitivity to cat allergens, ask your allergist before handling them…and before ruling them out
If you have a history of sensitive skin, don’t guess: random trial and error can cause more damage. Ask your dermatologist about a patch test.

Regularly published reports on the most common allergens by the North American Contact Dermatitis Group and European Surveillance System on Contact Allergies (based on over 28,000 patch test results, combined), plus other studies. Remember, we are all individuals — just because an ingredient is not on the most common allergen lists does not mean you cannot be sensitive to it, or that it will not become an allergen. These references, being based on so many patch test results, are a good basis but it is always best to get a patch test yourself.
