Humans can be sensitive to various allergens, and when the cumulative effect of these allergens exceeds an individual's allergen threshold, it can trigger a sensitivity reaction. In recent years, there has been a noticeable increase in the number of people with heightened sensitivity to substances such as plant pollen, certain foods, drugs, and others. Surprisingly, at a global level, it has been found that as many as 1 in 5 adults are sensitized to cat allergens.
