WhiskerBlock Alpha

WhiskerBlock Alpha is a bioengineered protein technology developed by Pacagen that utilizes single-domain antibodies (sdAbs) to neutralize Fel d 1, the primary protein responsible for cat allergies. The technology is available in two consumer formats: a neutralizing spray for environmental surfaces and an oral supplement (food topper) for cats. By binding to Fel d 1 at the source or in the environment, WhiskerBlock Alpha inactivates the allergen before it can trigger allergic symptoms in humans. It is marketed as a safe, food-grade consumer product rather than a pharmaceutical drug, designed to reduce environmental cat allergen exposure by up to 98%.
