First, you should understand the different symptoms of a cat allergy. The most common include swelling of the eyes or itching along with congestion or sneezing. These can help you determine whether you are allergic to cats or not. If you are allergic, these symptoms will appear in the initial phase.
You need to observe whether your skin is alright while you are with your pet cat. If you start to scratch your skin or observe any redness, you may be allergic to your cat. It is simple to find out if your cat is causing your skin irritation by simply staying away from your pet for a few days and if your skin clears then it is obvious.
Skin allergy test
If you are unsure whether you have an allergy or not despite the symptoms, you need to get a skin allergy test. The allergist will apply animal proteins to a part of your skin and if itching starts, you are allergic to cats.
A blood test will also determine whether you are allergic or not. The test will screen for antibodies in your blood that are the main cause of allergies on your skin. This test may be used when you cannot have a skin allergy test. Some people cannot have an allergy test as their skin can suffer a serious reaction so they undergo a blood test instead.
