Amazing stuff
I was afraid I'd have to get rid of my cats. I've been using for 2 months now. No sneezing or itchy eyes. They even sleep next to me at night & no problems!
- Cindy M.
Buying again
I honestly was a tad skeptical but I'm no longer sneezing or itchy and my sinus congestion is GONE! I'll be a repeat costumer for sure.
- Alexis N.
No more watery eyes!
I can’t believe how much of a difference this cat topper has made! I’ve always loved my furry son, but my cat allergies made it tough to give him all the cuddles he deserves. Ever since I started adding this topper to his food, I’ve noticed a huge improvement — way less sneezing, itchy eyes, and congestion.
- Jeanette
Works and Cat likes it
My cat is super picky so I was worried he wouldn’t eat it, but after a few days he came around and spent seem to notice it now. It also works, my allergy symptoms of itchy eyes, runny nose, and sneezing went away fully after a month.

I can snuggle our cats!!
Since I was a kid I've had to carefully pet cats, keeping them away from my face and then rushing to wash my hands. Since we started using the food topper I've been able to fully snuggle and cuddle our two cats! They even snuggle up to my face and no streaming nose or hives! It's amazing! This stuff really works!
- Naomi H.
Daughter's Allergies are better than anticipated
This seems to be helping with my daughter's allergies. We've had them since September of 2024 and she doesn't break out in hives or wheeze. She is super excited since cats have been her favorite her whole life and this allows her to be near them.

Skin reactions completely gone
I used to break out in hives whenever I was around cats for more than a few minutes. After using Pacagen, my skin stays completely clear. It's like magic!
- A. Garcia

It’s a miracle!!!
I was willing to suffer with allergies so I could add a beautiful ragdoll kitten to my home. But then I saw an ad for Pacagen Food Topper. Within a couple of weeks of using Pacagen on my kitten’s food, Charlie is able to sleep next to me on his pillow with no allergic reactions from me!
- Julie H.
No more sneezing!
We've been using the cat food topper since our new kitty came home from the shelter in February and it has made an amazing difference for both myself and my husband. Zelda likes the taste and our allergies are FAR less than with our last cat of 13 years…what a difference…no more sneezing and she even sleeps on our bed!
- Susan W.
It works!
Works great! Really helps with my allergies and we can sleep with my cat and cuddle with him with no worries.
- Grace K.
This product is a MIRACLE!
My kids and I have been severely allergic to cats for years. Now, my daughter was able to sleep in the SAME bed as one of the cats and didn't sneeze once for over 30 hours.

No longer a skeptic
I was resolving myself to a life of allergy meds, when I thought I'd try Pacagen. It worked!! After a couple weeks of my kitten using the food topper. (Which she loves!) My sniffles and sneezes went away! I'm a believer! I give her a tiny amount, just 1/8 teaspoon on her food morning and night, and now I can snuggle my cat and breath a relaxing sigh. Thanks Pacagen!
- Sandra V.
I love my new tabbies but was over all the morning sneezing and itchy nose. So, I tried this spray and the food topper. Genius! Symptoms so much better!
- Kim P.
Works great!
My husband finally isn’t miserable and sniffly around our cat! This is a game changer.

Works well
My son is allergic and has had major asthma issues for almost a year now. Since starting Pacagen, we've noticed that if one of the cats curls up on my son's chest, my son no longer is wheezing when he wakes up. His coughing during sports has lessened dramatically so far.
- Leslie D.
No problems
I put the powder on my cats for for two weeks prior to arrival ; and the week of friends visits. My friend did well. This is despite Emmys insistence on sitting on her chair ; and walking on table to address my friend face to face. Emmy loves the taste of it as well. No eye watering. No sneezing, coughing , no Problem!

Cat Allergies
Pacagen has worked wonders on my cat allergy. I was told by an allergist I was severely allergic to cats and walk on the other side of the street if I saw a cat. Using Pacagen has relieved my itching eyes, runny nose, sneezing and coughing so I can enjoy my rescued cat without any symptoms. Pacagen food topper is excellent.
