Here's what the Pacagen Community is saying
Allergen control has advanced beyond allergy pills & allergy shots.
At Pacagen, we've dedicated our research and development not on finding ways to mask allergies, but instead on breaking down allergens at their source - before they can enter your body.
Number of allergens living in your home
Pacagen neutralizes up to 98% of cat allergens
Meet WhiskerBlock™:
Our Novel Active Ingredient
What It Is
WhiskerBlock is our active ingredient with the sole purpose of targeting and shutting down cat allergens. Just like any other protein, it's completely edible and digestible.
How It Helps
Your cat allergies are due to the allergens that cats produce in their saliva. These allergens are often invisible to the naked eye and can cause discomfort without warning.
That's where WhiskerBlock comes in. By making contact with saliva in a cat's mouth, it neutralizes up to 98% of active allergens.By reducing the number of allergens so significantly, you can finally relax in a healthier home.
