Exposure to animal dander (dead skin that is continually shed) as well as animal urine and saliva causes human allergic reactions to animals. These reactions can make asthma, rhinitis and/or eczema (atopic dermatitis) symptoms worse in some people.
Animal Types
The dander, urine and saliva of feathered or furry animals such as cats, dogs, birds and rodents (hamsters, gerbils, mice etc.) can cause allergy symptoms. Exposure to other warm-blooded animals, such as horses or cattle, or to products made with feathers or down, may also cause allergy symptoms. A person can develop allergies with repeated exposure.
