ABSTRACT
I. INTRODUCTION People come into contact with animals in many different occupations and activities. In the indoor environment, household animals are significant sources of allergens. Cat and dog allergens have been especially recognized as being associated with allergic disorders, including asthma. Exposure to these allergens is perennial and is not limited to immediate contact with the animals. As people in industrialized countries spend some 90% of their time indoors, it is not surprising that sensitization is common.
