Some people suffer from allergies that are not chronic and can be avoided only by keeping specific breeds of animals. Animals that lower the risk of such allergies are known as hypoallergenic that could be dogs or cats. You can get physical and psychological benefit by keeping an emotional support animal. Some cats have allergies and produce them in saliva, while this attribute is absent in hypoallergenic cats. Such cats also have small hair with no risk of affecting a person with an allergy.
