More than half of dog and cat lovers share their beds with their fur babies. But if you have asthma or allergies, episodes triggered by animal dander and body fluids aren’t warm and fuzzy. Birds, and small rodents like hamsters and guinea pigs, appear on the allergy most-wanted list, too. If allergies get to you, keep pets out of your bedroom as much as possible, and off furniture. Be super-thorough when you clean.
