( provokes the body into producing histam...)Allergic Individuals Should Keep Away from Cats, Say UK Scientists,Health

provokes the body into producing histamine, a protein.

The histamine produces swelling and irritation of the upper airways and causes typical hay fever and asthmatic symptoms.

People who have had asthmatic bronchitis as children in a household with pets, especially a cat, are at a high risk of developing allergies towards cats as they get older.

Cat allergen is present on very small particles that readily become airborne when disturbed and are easily inhaled.

When a person experiences an allergic response, a chemical called human immunoglobulin, or IgE, produced by the immune system in response to the presence of allergens such as cat hair, binds to specific receptors on the surface of immune cells. This triggers the release of histamine in the body, causing symptoms such as itching, sneezing and runny eyes and nose.
