Pick Your Symptom
I purchased the Pacagen spray and food topper and have seen a noticeable difference with my allergies! I have been sneezing so much less. I had to go off my allergy meds for ten days and Pacagen was a life saver during that time. Plus my cat seems to love the food topper!
- Caroline L.
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.
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!
- Sandra V.
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 N.
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.
- Marguerita D.
We recently got a kitty from a local shelter and our daughter suggested using pacagen on her food to reduce our allergies, which we have had with other cats in the household in the past. So far, we seem to be sneezing less, no nasal congestion and our kitty likes the taste on her food.
- Susan W.
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!
- Renee B.
I am using the spray and the food topper to ensure effectiveness because my husband, who is allergic to our cat does like to take any medication. It has relieved his allergies (mostly coughing) almost completely!
- Amber J.
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.
The Pacagen food topper is a game-changer! It lets me feed my cat wet food without any worries, and I’ve noticed that my sleep has really improved
- Emma M.
I am so happy to report that this helped relieve most of my symptons - itchy/watery/burning eyes, and sneezing, stuffy/runny nose. Now I can sleep at night
- Kyle H.
Ever since I started using the cat food topper, my symptoms have been so much better and I can actually sleep well. Thank you!!
- Sarah S.
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.
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.
- Sara S.
My husband is allergic to cats and will break out in hives on his arms & his eyes will get puffy in his sleep. We tried so many different brands that are supposed to help and nothing really was sustainable. This cat food topper has worked for MONTHS! No puffy eyes or itchy arms.

Customer Reviews
My husband is seriously allergic to cats, and I never thought I would be able to live with cats again. Enter Pacagen. We decided to give Pacagen a try with kittens…and it has been life changing. We have been using the topper and room spray for about six months and it is worth every penny. It’s not a miracle, so we still take other steps to minimize allergen issues—no cats in the bedroom and frequent brushing. Those steps combined with Pacagen topper and room spray mean that he can snuggle with cats, sit on the same furniture, and enjoy their company without allergies. Plus the customer service has been fantastic!
To start, my cats are FIENDS for this. They know when it's time because it hangs out in one spot in the kitchen and they will stare at me while I prepare it, and they lick it up in seconds. I've definitely noticed a difference in my allergies, they're not gone completely but they've gone down a lot and I feel like I can finally enjoy snuggling my kitties again without worrying that my eyes and lips will puff up. It's become part of my waking up and going to bed routine. I love this stuff but my cats love it more. Pictured: Chicken, now 50% less allergenic, waiting for his yummies. Finn getting extra snuggles since I don't get red, puffy, and itchy.
Began with the spray allergen neutralizer, and have just begun the food topper. Cat loves it and my partner, who has the severe allergies to cats, has not had any issues in the 7 months since the cat adopted us and he now caters to the little critter. Thank you for this amazing product.
My mom visits every year and usually can't breathe because of my cats after about the 2nd or 3rd day. I've been using the pacagen power on my cats for 2 months and she's been here the last month with NO symptoms! I am so grateful!
My boys have been on the topper for right at a month now. I haven't noticed a huge difference but understand that it can take longer to see the effects. They weren't sure of the taste in the beginning but really seem to love it now.
I've been really impressed with their customer service as well! Will definitely update in another month or two.
