removes 98% of active cat allergens!
Introducing our Cat Allergen Neutralizing Spray, which proactively shuts down accumulated allergens.
LOVED BY CAT OWNERS EVERYWHERE
I've tried just about everything - from every allergy medicine out there to HEPA air purifiers in every room and vacuuming religiously. After a particularly bad week with allergies, I bit the bullet and bought Pacagen. And luckily, it worked out very well for me. I particularly love how the product doesn't need to be sprayed on the cat.

I’ve used Pacagen for about a month now and have definitely noticed a difference in my allergies around my house. I like that the spray helps me target specific areas of the house, and compared to some other dander reducing sprays, has no strong invasive smell. The bottle is still going strong and I’m happy to be more comfortable around my house!

I generally don't have cat allergies but my beautiful and sweet long haired cat makes my eyes itch and gives me nasal congestion when she sleeps with me. I tried Pacagen spray in my bedding and now have no issues with kitty joining me in slumber. Thank you!!!

We do A LOT to mitigate cat dander—liveclear allergy food, HEPA air cleaners & vacuums, regular brushing, routine laundry, etc.—but I am always still suffering. [...] But bottom line is that I have noticed a significant reduction in my allergies since using this product.
- Peter
My husband began hinting at rehoming or making our cats "fully outdoors," until we got Pacagen. He used to be awake for hours at night unable to breathe and that has now stopped almost ENTIRELY. Pagacen is a little pricey but worth EVERY PENNY. Don't keep suffering, it works!
- Katie
Purchased it for friends with cat allergies, and it's been smooth sailing. Simple to use, highly recommend since it eliminates the need for pills.
- Jeffrey
I used this in conjunction with a deep clean and putting an air purifier in our bedroom while my husband was away. When he returned his allergies were so much better, and we no longer had to keep our 2 new kittens out of the bedroom! It has been almost a month now and he is still doing great.
- Cynthia
My wife is allergic to our two cats and was considering getting allergy shots. I found an ad for Pacagen online and decided to try it out. Within the first hour, she felt a noticeable difference. She breathed better and could even have our cats around us when we were having dinner.

clear days await

"Existing treatments are invasive shots and pills that aren’t much help [...] But one start-up called Pacagen is finally changing all that"
"This spray works proactively to ensure symptoms never manifest”
how it works
Cats produce an allergen called Fel d 1 in their saliva. This is what causes cat allergies.
We engineer proteins called nanobodies that can bind to and neutralize these cat allergens!
We put these nanobodies into sprays for easy use. Simply spray in the air and on surfaces every 2-3 days.
The result: up to 98% of allergens are neutralized, which means less sniffles and more cuddles!
How to use it
Find areas in your house that cats frequent, such as the couch, the bedroom, or nearby litter box.
Spray these areas generously with our Allergen Neutralizing Spray and wait 10-15 minutes for the nanobodies to work their magic.
Repeat this process every 2-3 days based on symptoms to enjoy your newly discovered cat allergen-free life!
The Science Behind Pacagen
Our search for a better way to manage cat allergens began with an unexpected key player: alpacas! Inspired by their unique immune systems, we developed nanobodies that have the remarkable ability to exclusively bind to Fel d 1 without affecting cats or people.
Through a binding mechanism only possible because of our nanobodies' unique structure, our products are able to reduce airborne Fel d 1 concentrations by up to 98%, making it the most effective cat allergen reducer available.
A Story Rooted In Love
Pacagen’s journey began with love at first sight. When Dr. Evan Zhao and Dr. Siyang Han welcomed their British Shorthair, Miaomiao, into their lives, their joy was quickly met with a challenge—Siyang’s allergies. Determined not to choose between her health and Miaomiao, Evan, a Ph.D. in Chemical Engineering from Princeton University, turned to his expertise. The discovery of nanobodies that neutralize allergens provided the answer.
The result? A cat allergen spray, safe for pets and people. “Now, we can enjoy Miaomiao without worry—and that’s what I want for every pet family,” Evan shares.
