Example: Rat Allergy
-
Psychologists who work with rats and mice in experiments often become allergic to these creatures. This is a real hazard for investigators who spend hours a week running rats in experiments. These allergies are a reaction to the protein excretions of rats when they get upset. Therefore it is recommended that experimenters be kind to rats and talk softly to them.
