Answer:
These animals are hypoallergenic meaning they will not cause allergies.
Allergies are caused when the allergens enter through some pore or through the respiratory tract but the fur of these furry mammals fly off in.. fluffs? They do not shed much.
When you first get one, it might because it is a defense mechanism. When it gets used to you, it will stop shedding as much. Tufts of hair only fly off if it is scared so will not cause allergies.
