Happy Cats. Sniffle-Free Humans.

Our son has a severe allergy to cats and has been receiving allergy shots for years. He gets watery eyes and a runny nose within an hour of coming home from college. We started using this with our cats 4 weeks ago...and he's no longer reacting at all!! He's breathing normal with NO SYMPTOMS.

Try Buckley Risk-Free

The Science Behind the Relief.

Buckley works by addressing cat allergens at the source. Cats produce the main allergen, Fel d 1, in their saliva. When they groom, that allergen spreads onto their fur and throughout your home.

Buckley contains a natural protein found in eggs called IgY. When your cat eats it, IgY binds to Fel d 1 in the mouth and helps make it inactive — so less allergen is spread during grooming.

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 cat owners report a noticeable difference in allergy symptoms after 30 days of consistent daily use.

Because Buckley is just a natural egg 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.

Developed With Veterinary Experts.

Buckley is developed alongside veterinary professionals to safely reduce active Fel d1 allergens at the source. Our IgY antibody process is backed by peer-reviewed research and designed to support allergy management without changing your cat’s diet.

"Buckley’s IgY antibody approach neutralizes Fel d 1 at the source and provides a safe, non-invasive option for managing cat allergies without changing a cat’s diet."

Frequently Asked Questions

You've got questions, we've got answers.

How exactly does Buckley reduce allergens?

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.

Will my picky cat actually eat this?

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.

Is it safe for kittens or cats with health conditions?

Yes, but we recommend that you check with your veterinarian first. Buckley is a non-medicated, food-based supplement made from one simple ingredient: egg yolk. It's safe for cats of all breeds and ages. We always recommend starting with a small dose and gradually increasing as your cat adjusts. In rare cases, some cats may have egg sensitivities, so if you have any concerns, your veterinarian is always the best resource.

How long does it take to see results?

While Buckley starts neutralizing allergens immediately upon consumption, it takes weeks to see the full effects. Most pet parents notice a significant improvement in symptoms within 4 weeks of daily use.

Can I stop using my air purifier or taking allergy pills?

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.

What if it doesn't work for me?

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 6 weeks), simply contact us at trybuckley@gmail.com for a full refund!

What happens if I miss a day?

Consistency is crucial because your cat produces saliva (and allergens) constantly. If you miss a day, just resume the daily scoop as soon as possible to get back on track.

Does it contain grain, soy, or artificial additives?

No. Buckley is a clean-label product. We use only essential, high-quality ingredients derived from pasture raised 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).
