Having a cat in the house with itchy eyes recently is most likely due to symptoms of eye irritation caused by animal hair that is cat hair. This condition occurs frequently and not occasionally, because the cat’s hair is continuously shed, so the itchy eyes should also be continuously present. Therefore, anti-allergy medication is required. Orotadine eye drops are usually used for symptomatic treatment of this allergy, and can also be combined with non-steroidal anti-inflammatory drugs, such as pralofen or diclofenac sodium for relatively stronger anti-allergy treatment. If the allergy is indeed caused by cat hair, you should keep a certain distance from the cat, so as not to touch the animal’s hair too closely, and the allergy symptoms can be gradually reduced.
