The Science Behind the Relief.
Buckley utilizes a targeted protein found in eggs (IgY) to neutralize allergens physically, not chemically. It is a non-systemic solution, meaning it works without entering your cat's bloodstream.
Our formula relies on a specific protein derived from eggs that naturally binds to Fel d 1. This is not a synthetic drug; it is a bio-functional food ingredient that targets the allergen structure directly.
Unlike antihistamines that alter body function, Buckley works on contact in the mouth. It simply coats and neutralizes the protein in the saliva, leaving your cat’s natural biology completely untouched.
While the neutralization happens immediately upon eating, reducing the existing allergen load in your home takes time. Most households report a noticeable difference in air quality after 21 days of consistent daily use.
Because Buckley is just a protein powder with no additives, it is safe for cats on prescription diets (e.g., urinary or kidney support) and won't interfere with other medications.

Frequently Asked Questions
You've got questions, we've got answers.
Buckley uses a specific protein derived from eggs (IgY) that naturally targets and neutralizes the Fel d 1 protein in your cat’s saliva. By neutralizing the allergen in the mouth, we prevent it from spreading to the fur during grooming, stopping the problem before it becomes airborne in your home.
Yes. Buckley is completely flavorless and odorless. It is designed to blend seamlessly with wet, dry, or raw food without altering the taste or texture. Even the most finicky eaters won't know it's there.
Absolutely. Buckley is a non-medicated, food-based supplement. It does not enter the bloodstream and is safe for cats of all breeds and ages. It is also compatible with prescription diets and other medications.
While Buckley starts neutralizing allergens immediately upon consumption, it takes time to reduce the existing allergens in your home environment. Most pet parents notice a significant improvement in air quality and symptoms within 3 weeks of daily use.
Many of our customers find they can significantly reduce or eliminate other allergy management methods after 3-4 weeks of using Buckley. However, every home is different, so we recommend adjusting your routine based on how you feel.
We offer a risk-free 60-Day Money-Back Guarantee. If you don’t feel a difference in your allergy symptoms after giving it a fair try (we recommend at least 3 weeks), simply contact us for a full refund. No hoops to jump through.
Consistency is crucial because your cat produces saliva (and allergens) constantly. If you miss a day, the neutralizing effect will pause, and allergen levels in your home may start to rise again within 24-48 hours. Just resume the daily scoop as soon as possible to get back on track.
No. Buckley is a clean-label product. We use only essential, high-quality ingredients derived from eggs. It is free from grains, soy, gluten, and artificial preservatives, making it a safe choice even for cats with sensitive stomachs (unless they have a specific egg allergy).
