To understand cat allergies, we need to delve deeper into what happens in our bodies when we encounter cat allergens. These allergens—often proteins found in cat dander, saliva, and urine—interact with our immune system, triggering allergic reactions.
Once these allergens enter our bodies, our immune system mistakenly identifies them as harmful invaders, releasing antibodies to attack them. This defense mechanism releases chemicals called histamines into our bloodstream, causing common allergy symptoms like sneezing, itching, and congestion.
