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 break down 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 broken down, 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 break down 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.

FAQs

Definitely! We made sure to use a completely pet-friendly approach when creating our formulas. Each part of the formula was hand-picked to be safe for everyone, four-legged or not, involved. However, it’s best to avoid spraying directly onto cats – mainly because cats usually don’t like getting wet. On top of that, the allergen-neutralizing nanobodies are always manufactured to food-grade standards.

The nanobodies are proteins, so they are subject to degradation when dissolved in tap water, as minerals and impurities can disturb the nanobodies’ structure. The Stabilizing Solution is formulated to preserve the nanobodies’ structure as long as possible without hampering its neutralizing properties.

We don't currently make a scent-free version. However, the scents included in our Allergen Neutralizing Powder are very mild and are included in very small quantities. Most customers report that the scent is close to unnoticeable after spraying.

Our products use the latest developments in biotechnology to provide you with a safe, pure, and environmentally friendly solution to your allergies. Internal testing found that our nanobodies are capable of neutralizing up to 98% of Fel d 1. Other products on the market are only able to neutralize up to 50% of Fel d 1. On top of that, our products are incredibly safe to use and are non-invasive to you and your pet’s routine.

The nanobodies don't expire, but they are most effective within 1 month of dissolving in distilled water. However, if you dissolve the nanobodies in our Stabilizing Solution, it'll be effective for up to 2 months.

Spraying frequency depends on a lot of factors, including how much Fel d 1 your cat produces, how severe your allergies are, and how sensitized your immune system is. We recommend starting out by spraying once every 2 days, then increasing or decreasing the frequency depending on if your symptoms are still present.

We take pride in the fact that our sprays are designed with environmental consciousness in mind. Where possible, we use biological ingredients that have no long-term environmental impact. In fact, 99% of the ingredients in the powder are biodegradable! We also make sure that all of our partners share a similar commitment to environmental consciousness.

For orders within the contiguous United States, we offer 3-day and 5-day shipping options. To Hawaii & Alaska, orders can take up to 8 days to arrive.

For orders to Canada, please allow up to 10 days for shipping, as CBSA processing times vary.

Impressed!

We purchased the cat spray (after lots of research into the company and product, as it is a bit pricey), because my husband has allergies. Despite doing our best to keep our home clean and fresh he was still having daily reactions. We thought, what do we have to lose? Within just a few days of using the spray he noticed he was feeling better and waking up without allergies! Huge game changer for us. We will be using this regularly!

Seems to be helping!

My son can now spend more time with family in the common areas instead of being sequestered to his "safe" room where the cats are not allowed. I've used the cat spray about 3 times, and it seems to have a building effect.

Works

A family member with strong cat allergies came to my house for dinner so in preparation, I sprayed all fabrics with Pacagen. She was able to go the whole 3 hours without developing any allergy symptoms! Great spray, thanks Pacagen!

Saved me!!

I have several recently developed health issues that preclude me from getting allergy shots or taking many allergy medications… so Pacagen saved me from having to get rid of my Maine Coon. He is a great companion and it would have completely wrecked me if I had to rehome him. Thank you Pacagen!

good to have on hand

I had a bottle at the ready since I am bedbound with severe ME as well as MCAS which is a mast cell disorder that can release excess amounts of histamine and other things you do not want in your body as it can make it painful and exhausted.

I was adopting a cat that I could not meet completely alone with without dealing with the dander of 30 other cats at the same time, so the true test would unfortunately be bringing her home.

I was itchy the first few days, but only about three out of 10. My caregivers sprayed pacagen a few times and I could definitely feel it. Bring the entire intensity of the itch down. I don’t know what happened if my medication (ketotefin) kicked in even more though I was taking half the usual amount, but now I am not itchy at all!

I wouldn’t have attempted this Adoption without having pacagen, and I’m very grateful that I had it in my back pocket and then it did take the edge off and that now somehow I don’t even need it anymore!
