WHAT IS FEL D 1?

Fel d 1 is a protein cats produce in their saliva, skin, and urine. When cats groom themselves, Fel d 1 spreads from their saliva to their fur, which is dispersed into the environment, causing a variety of negative health effects in the 20% of people who are sensitive to it.

About Fel d 1 Buildup

Over time, Fel d 1 accumulates in cat owners’ homes, leading to a highly allergenic environment. Fel d 1 particles are sticky and adhere to surfaces like carpets, furniture, and clothing.

Even after a cat has left an area, Fel d 1 can remain in an environment for months, continuing to trigger allergic reactions. One study found that Fel d 1 is so sticky, trace amounts can be found in up to 99% of homes– including ones where cats aren’t even present!

How to Manage Fel d 1 Buildup

For those sensitive to Fel d 1, managing it requires a multifaceted approach. Regular grooming reduces fur and dander, and bathing your cat, while not easy, also temporarily lowers allergen levels.

For a modern, science-backed approach, consider allergen neutralizing products that neutralize Fel d 1 on contact to prevent it from causing allergic reactions. With consistent effort, you can significantly reduce Fel d 1’s impact live more comfortably with your cat.

I just got my first cat a few weeks ago. I was taking 2-3 allergy pills a day. Now after this product I'm taking 2-3 a week. It seems to be helping a ton. It is definitely worth a try if you experience allergies.

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.

My girlfriend has severe allergies to cat hair (sneezing, running nose). The Pacagen spray actually works pretty well for her and along with some allergy relief pills, she’s completely okay to stay with our cat for a long time. Works great so far since I started using one month ago, hope it will be effective in the long run too!

A miracle cure to my cat allergies. Was never able to visit with my son & daughter-in-law who have two cats. Even with Zyrtec and Flonase I got itchy puffy eyes and face that lasted a day or two. With the addition of Pacagen, I was not only able to visit, but I actually slept in their home for 2 days/nights.

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.

how it works

Cats produce an allergen called Fel D1 in their saliva. This is what causes cat allergies.

Pacagen engineers proteins (called nanobodies) that can bind to and neutralize these 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 your cat frequents, such as the couch, the bedroom, or the litter box.

Spray areas generously and wait 10-15 minutes for the nanobodies to work their magic.

Repeat every 2-3 days based on symptoms, and enjoy your allergen-free life!
