    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!

    Amazing product

    This spray has truly helped out within my home. My brother and his wife both have cat allergies and it's tough for them when they visit. We spray this a couple of days before they visit, and he can be around the cat with no issues whatsoever. She still eventually has a reaction, but it is a noticeable improvement

    Thank goodness this works!

    I married into a family where almost all of them have mild to severe cat allergies, including one kid with asthma and a severe reaction to cat dander. We have a sweet cat, but no one but me can touch her. Using the spray, we noticed an immediate difference. We just spray before anyone visits, or quickly once they're here, and there have been no reactions. No one has had to leave!

    Long time allergies GONE

    I used to tell my daughter she’d never have a pet, but I have a ragdoll now and we only got him because there’s options to manage my allergies. He’s been on Pacagen since he was 8 weeks old. Now he’s a year old, and I’m honestly amazed. I never thought this would be possible!

    Breathing easier, both of us, and I didn’t think I was allergic

    My wife has had serious asthma all her life, and that's a long time. We’re both well past retirement aged . When we got together 25 years ago, I had had cats all my life, and I converted her to a Cat Person. She’s had cat-allergy symptoms that occasionally get hard to bear all this time.

    Just under two weeks ago we received our first Pacagen shipment. My wife’s allergic symptoms are noticeably diminished; late-night coughing and itchy eyes haven’t been a problem. I’ve never thought I was allergic to cats at all, but T o my surprise, my nose and sinuses are more comfortable than they’ve been in the past, and my eyes as well. Thank you. You’ve earned a couple of long-term customers.

    Amazing product

    I have had allergies to cats for 50 years. But, I am a cat lover to my core. Some cats do not bother me at all, while others do. I had 2 cats and rescued a female 2 winters ago. She had 4 kittens; two found homes and the other 2 adopted us! So, now I have 5 cats! Pacagen is my lifesaver.
