Allergy to cats
Cat allergy in humans is an allergic reaction to one or more allergens produced by cats. The most common of these allergens are the glycoprotein Fel d 1, secreted by the cat's sebaceous glands and Fel d 4, which is expressed in saliva. An allergic reaction is a histamine reaction that is usually characterized by coughing, wheezing, chest tightening, itching, nasal congestion, rash, watering eyes, sneezing, chapped lips, and similar symptoms. In some severe cases, reactions may progress rapidly to
Fel d 4 (a lipocalin). The minor allergens include Fel d 2 (an albumin), Fel d 3 (a cystatin), and cat IgA.
Fel d 4 is the product of the cat major urinary protein gene. It is primarily expressed in the submandibular salivary gland and is deposited onto dander as the cat grooms his or her self. A study found that 63% of people allergic to cats have antibodies against Fel d 4.
