4. Animal Allergies

According to the Humane Society of the United States, about 15% of the country’s population is allergic to cats or dogs. Other animals that cause allergies are rats, mice, rabbits, and guinea pigs. Insect bites and stings can also trigger an allergic attack, with bees, wasps, cockroaches, mosquitoes, ants, and scorpions being the most common culprit. In pets, the most common cause of an allergic attack is dander or dead skin cells, while in rodents cause allergies through saliva and urine, in addition to dander. As for insects, it’s the venom from their sting or bite that causes the allergic reaction.
