Most sprays attack everything in your home. Pacagen does the opposite. Using WhiskerBlock™ technology, it neutralizes Fel D 1, the specific protein responsible for cat allergies, protecting both you and your cat without unnecessary chemicals.
60-Day GuaranteeScience-BackedSafe For Pets

Unlike generic sprays that attack all proteins indiscriminately, WhiskerBlock™ zeroes in on Fel D 1, the protein that actually triggers your allergies.
Because it's targeted, there's no unnecessary chemical exposure. Safe for humans and cats, you can spray anywhere your cat roams, bedrooms, living rooms, or favorite lounging spots.
WhiskerBlock™ works on surfaces and in the air, providing full-room protection from allergens. Finally, a solution that covers everyone at once: no pills, no fuss.
Developed by Harvard-trained scientists and backed by over $2 million in biotech research, Pacagen is precision-engineered to neutralize the protein that actually causes your symptoms.
Snuggle, play, and live with your cat freely. No grogginess, no prescriptions — just a safer, allergen-reduced home that works for everyone.

Every time my daughter would come visit our home, our 2 cats would make her sneeze. I tried the Pacagen spray on all the areas the cats like to lay (rugs, couch, chairs, etc.) and after only a few times, she said she felt much better. No more sneezing! I'm a believer!!

“Pacagen’s approach is exciting because it focuses on the source of the problem itself. As a dermatologist and educator, I’m always interested in science-driven technologies that help make patients' environments healthier and more comfortable.”

“Many people swear by this antibody additive, which can be directly applied as a topper to food. The brand most recommended to me was Pacagen, a powdered additive that should be added to food or fed twice daily.”
