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.

Noticed a difference almost immediately with the spray!

We have been using the food sprinkles for a couple of months now, but when I added the spray for cat allergens, chef's kiss!

Happy to see this product exists!

Although my cat allergies still remain, I believe the food cat topper has helped since I began allowing my cat to sleep in the bed with me and will continue to purchase. I also have used the allergen spray with similar results.

Hi Laurel!
Thank you so much for taking the time to share your experience with us. We're really grateful you've given both the Cat Food Topper and the Allergen Neutralizing Spray a try — and even more so to hear that they've helped enough for you to feel comfortable letting your cat sleep in bed with you. That’s such a special bond, and we're honored to play even a small part in making that possible.

We know cat allergies can be stubborn and frustrating, and while we’re so glad to hear there’s been some relief, we want to help you maximize that progress as much as possible. Here are a few extra tips that many of our customers have found helpful in reducing allergens in the home:

- Use the spray consistently: Spraying the neutralizer every 2–3 days on high-contact areas like bedding, furniture, and rugs can make a big difference. Light, even sprays are enough — no need to soak.
- Vacuum with a HEPA filter: Regular vacuuming with a HEPA-equipped vacuum can help trap and reduce allergens like dander.
- Wash bedding frequently: Try washing your bedding and your cat’s bedding weekly in hot water to remove any lingering proteins.
- Air purifiers: If it’s an option, running a HEPA air purifier in your bedroom or living space can reduce airborne allergens significantly.

We hope these tips help amplify the impact of the topper and spray! And please know we're always here for any questions, concerns, or just to support you on this journey. Your feedback helps us get better, and we’re truly thankful for your trust and honesty.

With gratitude,
The Pacagen Team

Life changing

My wife has (or shall I now say “had”) severe cat allergies. Pacagen has changed our lives! We have two large long haired cats and without Pacagen she would be absolutely miserable. As it is, she had minimal to no symptoms and can enjoy picking up, petting, and snuggling with our two cats. This was an impossibility before Pacagen. Thank you for making our furry family possible!

Hubby was allergic to our cats

This stuff is amazing! Even my skeptical husband has to admit it works. Runny nose? Ha! Not any more! Puffy eyes? Not even! Just spray areas where cats hang out, and enjoy clear breathing! 💕
