Want a pet cat? Think again, researchers say
(Reuters) - Tempted by the playful antics of that adorable kitten in the pet shop? If you've never had a cat before you may want to think again, especially if you have other allergies, researchers warn.
And if you do acquire a feline, keep it out of your bedroom.
While having a cat as a child may protect against future allergies, getting one in adulthood nearly doubles the chances of developing an immune reaction to it -- the first step towards wheezing, sneezing and itchy eyes, a European study found.
The same study, which covered thousands of adults and was published in The Journal of Allergy and Clinical Immunology, found that people with other allergies were at extra high risk of reacting to a new feline in the house.
"Our data support that acquiring a cat in adulthood nearly doubles the risk of developing cat sensitization," wrote Mario Olivieri, from the University Hospital of Verona in Italy.
"Hence, cat avoidance should be considered in adults, especially in those sensitized to other allergens and reporting a history of allergic diseases."
For the study, researchers surveyed more than 6,000 adult Europeans twice over nine years, taking blood samples. None of the participants had antibodies to cats in their blood to start with, meaning they were not sensitized to the animal's dander.
Sensitization can be measured in a skin prick test. It does not necessarily lead to symptoms, but in many cases it is the harbinger of full-blown allergies.
About three percent of people who did not have a cat at either time of the survey became sensitized over the course of the study, compared to five percent of those who acquired a cat during those nine years. Continued...
