    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!

    So far so good

    I am still working through my first bottle. While I thankfully don't have cat allergies, others in my life itch when around my fur babies for too long. So far spraying the couch and other soft surfaces every few days has decreased this allergic reaction. I'm hopeful we will continue to see improvements over time.

    My daughter was able to visit with no sneezing or congestion!

    We recently adopted a cat and I needed to find a solution to help with the dander so my daughter could visit for a week. She will immediately know if a cat is present in a room by the allergic reaction she has. I sprayed the Pacagen spray for cat allergies and she was able to stay the whole week without any symptoms!

    It’s amazing!

    As I get older, I’m becoming more susceptible to the cat dander. My boyfriend is also incredibly allergic to cats and we just moved in together. He gets hives, gets super itchy, the whole thing. I decided to give Pacagen a try. Let me tell you, this stuff works INSTANTLY. My boyfriend can now pet my cats and doesn’t have to worry.

    My Boyfriend Stopped Complaining

    My boyfriend’s cat allergies check all of the boxes, itchy eyes and skin, congestion and runny nose, hives, and sleeplessness due to those symptoms. I’ve tried one other allergy relief remedy and it didn’t make any difference. From the start of me using the Pacagen spray he has felt better, to the point where he stopped complaining about how terrible he feels around my cat. I spray the whole house every day, it’s amazing stuff. It does rapid and lasting relief. Sensitive for all animals and all surfaces of your house. The unscented spray smells very slightly like vinegar then the smell fades almost immediately. I recently started using the food topper and my cat LOVES it!

    Seems to work

    I have only been using the product for almost two weeks but my coughing has improved and my husbands sinus drainage hasn’t happened as often. I am looking forward to our symptoms to continue to improve.
