HEALTH UPDATE: cats may be trouble for any allergy sufferer

People with allergies may have some constriction in their airways when they're around a cat, even if they're not specifically allergic to cats, a study published Monday suggests.
Researchers found that people with a range of allergies - to grass, mold or dust - were more prone to airway constriction if their homes were heavy with cat dander. This was true even when blood tests showed the allergy sufferers were not specifically sensitised to cats.
While the airways of the lungs naturally constrict to some degree in response to an irritant, exaggerated responses are seen in lung conditions like asthma.
