Allergy to cat hair is a common reaction caused primarily byproteins in cats'saliva, urine and sebaceous glandsthat are deposited on their fur.
When cats lick themselves, these proteins stick to the fur and, once dried, can become part of the environment in the form of allergens.
These small particulates can be inhaled by humans, triggering allergic reactions that include sneezing, itchy eyes, rhinitis and, in more severe cases, asthma. Management of this allergy often includes measures such as keeping the house clean, using air filters, and dietary solutions such as LiveClear®, which reduces allergens on cat hair.
