Pet allergies are certain proteins (allergens) on your pet that cause your allergic immune system to overreact. Usually, these allergens are harmless. But if you have pet allergies, your allergic immune system views them as harmful “invaders” that it must get rid of.
The most common cause of allergy is pet dander. Pet dander is tiny scales from your pets’ skin, fur, hair or feathers. But other sources of pet allergens include animal:
- Fur
- Saliva (spit)
- Skin
- Urine (p*e)
Any pet can produce allergens. But cats and dogs are the most common source of pet allergens.
