Why You Need To Neutralize Cat Allergens At Home

We love our cats, but cat allergens are ultra-fine particles that cling to our pillows, upholstery, and air. Left unchecked, they can wreak havoc on more than just your nose and eyes.

My daughter didn't sneeze!

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!!

Fantastic product that really works

We had a person stay over for 3 nights in our house with 2 Siamese cats. She is highly allergic to cats. Not a sniffle, sneeze, itchy eyes. NOTHING! Miraculous.

It works!

Thanks to this spray I was able to have my friend over who previously couldn't visit without severely watery eyes. Now she can comfortably sit on my couch in the same room as my cat!

It worked!

My grandchild and son-in-law, both of whom are allergic to cats and are always uncomfortable in our house even with taking medication, spent ten days in our house with NO symptoms and without their meds. I sprayed before they arrived and every other day while they were here and never heard a sneeze or saw a teary eye.

Great product

I have 2 cats that I love, but one of them gives me allergies, and between seasonal and cat allergies I was dying, sneezing, coughing and swollen eyes :( but after a few weeks using this product my life has changed, no more sneezing and overall no more red, swollen eyes.

Works for 4 Cats!

You can hot mop your hard surfaces which helps but I was losing to the soft surfaces. Pacagen made a huge difference. It actually works. I love my cats. Pacagen has relieved quite a bit of allergies and stress. I don't worry about what to do if my kids have allergy. I feel confident no one will be shipped off to grandma's house over cat dander

An actual life saver!

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 on strong and I'm happy to be more comfortable around my house!

Surprisingly works

My spouse has severe allergies to cats but loves them. With this spray we can sleep with our two cats in our bed and she can sleep through the night with no issues.

Finally relief!!!

My partner has a cat and I couldn't ever go to their place. But not anymore! I bought the starter pack and walked into the apartment spraying everything. It went so well that I'm at their place all the time now. I can even tolerate the cat sleeping on the bed with us. This stuff is a game changer and I highly recommend!!!

Amazing life saver.

It really helped my sudden eczema reaction caused by cat allergens immediately. Life saver. This is enabling me to keep my fur babies, even in a studio where my cats often sleep with me. I take the spray to my friends' place with cats too and I can hang out just fine. Thank you!

Incredibly Helpful

I have only been using Pacagen for a short while and have already noticed a difference in my allergies. Use of Pacagen in combination with increased vacuuming have led to a noticeable positive effect when I use the spray and I have stopped having issues with rashes and stuffy noses caused by allergies to my cat.

- A. Bruno

My Husband Can Breathe Again!

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!

Can’t believe how well it works!

I started dating someone with awful cat allergies. The first time he came over, he was sneezing nonstop and had to leave within 20 minutes… We tried Pacagen with low expectations, but holy cow—it worked! Last night, he stayed over with the cat sleeping on my pillow next to him. He could pet the cat and enjoy himself. Worth every penny for the quality time. Thank you, Pacagen! Now, if only you’d sell the cat food topper in Canada!

A Miracle

My mom has always been severely allergic to cats—she couldn’t even step into a home that used to have one without her eyes swelling shut… So I never had a cat.

I moved to Florida and started fostering. When she visited for Christmas, I was worried she wouldn’t be able to step inside. I had been using Pacagen for a month, sprayed before she arrived… and it WORKED! I could cry, I’m so happy. Subscribing for life. Wish it was cheaper, but it’s worth every penny.

“CAT”tastrophe averted...

My husband’s cat allergies are so extreme that his eyes swell shut and his airway constricts within hours. Allergy pills were useless. After researching, I found Pacagen and decided to try it.

At first, we didn’t tell my husband—he thought his allergies had miraculously disappeared until the Pacagen wore off, and symptoms returned within 15 minutes. Now, we spray regularly, and he can finally visit our daughter’s home without issue. If it works for him, it’ll work for anyone. Pacagen is a miracle!

When you’ve tried everything– try this:

This product worked really well for me. I was previously using an anti-allergen cat food but had to stop because I needed to switch my cat to a prescription food. This product came at just the right time and has worked consistently better than any other product I’ve tried so far (cat shampoos, cleaning wipes, hepa filtration, anti-allergen cat food etc.) Those products did help a bit, but Pacagen made an immediate and significant difference. Will be continuing to purchase this product.
