Allergies to cats, a type of animal allergy, are one of the most common allergies experienced by humans. Among the eight known cat allergens, the most prominent allergen is secretoglobin Fel d 1, which is produced in the anal glands, salivary glands, and, mainly, in sebaceous glands of cats, and is ubiquitous in the United States, even in households without cats.[1] The second most common is Fel d 2, this type is triggered by the cats dead skin flakes (dander) that are floating in the air as well as in the smell of cat urine.[2][3]
Allergic symptoms associated with cats include coughing, wheezing, chest tightening, itching, nasal congestion, rash, watery eyes, sneezing, chapped lips, and similar symptoms. In worst-case scenarios, allergies to cats can develop into severe respiratory symptoms such as rhinitis and mild to severe forms of asthma.[1] Despite these symptoms, there are many types of solutions to mitigate the allergic effects of cats, including medications, vaccines, and home remedies. Hypoallergenic cats are another solution for individuals who want pets without the allergic consequences. Furthermore, prospective pet owners can reduce allergic reactions by selecting female cats, which are associated with lower allergen production.
