Abbie discovered new realms of discomfort via cat allergies.

"Fel d I", the cat allergen, is the major cause of allergic reactions to cats. During a cat's self-cleaning process, Fel d I protein in the saliva is deposited on the fur. It is also produced by sebaceous glands--the skin glands that secrete the oils that keep the skin and hair sleek and shiny. Male cats usually produce more allergen than females. Proteins in the urine of cats will also trigger allergic reactions.
