Exposure to animal dander (dead skin that is continually shed), animal urine and saliva can cause human allergic reactions to animals. Examples of allergy symptoms include itchy eyes, runny nose, and rash. 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, also may cause allergy symptoms. A person can develop allergies with repeated exposure.
