    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!

    Really works!

    Been putting up with itchiness because I'm allergic to cat dander. Sprayed this around and no more itchy!

    Working great!

    I looked at the ads for Pacagen on social media for several months before I tried it. Both the spray and the topper are working really well - my son, who visits often and is very allergic to the two cats, used to live on Benedryl while with us, and still was stuffy and wheezy. The wheezing has stopped while he's here and the stuffiness has been reduced as well. I use the spray 3 times a week, and so it is lasting well - 2 months in the refrigerator as directed. That makes it economical as well as effective.

    Seems to be working so far

    I bought this to reduce my husband's allergic reaction to our cats. His symptoms have reduced over the last month and we're going to continue using it for the time being. My mom bought the dog product for her apartment and after spraying it, my husband was able to stay there for an entire evening without itching.

    Honestly, this works!

    My cat allergies are not very serious so I manage fine with pills, however I had a house guest with way worse reactions so I panicked and bought Pacagen. This worked within 24 hours!! My guest and I didn't even need to bother with pills for an entire month. 100% recommend.
