    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.

    Why Stop Allergens?

    The allergens your cat sheds are the root cause of your allergic flare ups. Remove those allergens, and your body will thank you in ways you didn’t expect!

    Great Customer Service

    Pacagen has been extremely responsive. When I inquired as to the efficacy of the product for people with asthma, I received an honest answer, saying they were still needing more data before having any clear conclusions. Also, they were helpful with a shipping cost when there had been trouble with the website. Excellent customer service.

    Seems to be working

    I don’t have cat allergies but my son in law is very allergic to our two cats. We’ve been using pacagen for a couple months now and he feels it has helped, he doesn’t sneeze or get itchy eyes immediately like he used to.

    Very effective.

    I began having my community of cats, and experienced really bad allergies and I was about to re-home them. Fortunately, I came across with a Pacagen AD, and I gave it a try, and thanks be to God and I’ve kept my kitties and allergies have lowered considerably.

    Haven't tried it yet but looking forward to it!

    I developed rather bad allergies, and I've had the solution for some time but my cat is yet to move in back with me. When he does and I try, I'll update my review! I'm looking forward to it so much!

    So far so good!

    My husband has cat allergies an. I purchased the cat Pacogen to try - we've definitely experienced some relief over the past 3 wks. I think we're going to try the dust Pacogen next because we both have dust allergies!
