Pacagen uses WhiskerBlock™ technology to neutralize the primary allergens causing cat allergies. One spray makes your home allergy-free for up to 3 full days!
Instantly relieves cat allergens and reduces flare-ups – for yourself and your guests.
Pacagen Cat Allergen is the first spray to feature WhiskerBlock™ technology. This non-toxic solution specifically targets the primary cat allergen: the Fel d 1 protein.
All it takes is one spray to neutralize cat allergens for up to 3 full days. Pacagen stays in the air, breaking down any Fel d 1 in its vicinity to neutralize cat allergies around the clock. And there are zero side effects for humans OR pets!
It took us $2 million of investment and years of collaboration between top veterinarians and doctors to create Pacagen… all for the love of cats!
Unlike other options that only try to manage symptoms after they appear, Pacagen targets allergy outbreaks before they ever begin.
It neutralizes 98% of cat allergens, keeping active Fel d 1 below the threshold that triggers your immune system—so symptoms never start.
Only Pacagen truly protects your home from allergy outbreaks, before they start.
Pacagen will NEVER make things worse – because it’s completely non-toxic and safe to use at all times.
It was formulated with and reviewed by board-certified veterinarians and allergists, and is extensively lab tested in internationally certified facilities for efficacy, quality, and safety.
Unlike antihistamines and shots, nothing enters your body. All it takes is a single spray in the air to prevent allergies!
Pacagen will never damage your furniture or leave behind a mess of any kind. It simply disappears after a few days without a trace!
Because Pacagen’s key ingredient only targets the primary cat allergen protein, it has no effect on any other part of the body.
It’s so simple, a cat could do it – if only they had thumbs!

Backed by $2M in research and development, Pacagen was developed by a team of researchers led by Dr. Evan Zhao and Dr. Siyang Han, a husband-and-wife team of scientists and cat-lovers.
They formed a world-class team of doctors, veterinarians, and scientists from Princeton, Harvard, and Cal Tech to create the perfect solution for cat allergies. The result is Pacagen and its key ingredient WhiskerBlock™ – the first and only way to neutralize cat allergies at the source!
Today we’re proud to say that over 100,000 families with cat allergies trust our veterinarian & allergist recommended formula… and counting!
