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!

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.

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
I'm happy to report that both of my cats enjoy the taste of the Topper. This, along with the spray, make my home much healthier for allergy sufferers. I've had friends come over and ask if we had got rid of the cats, because their usual allergies weren't triggered. Nope. My cats are also my family!
I cannot believe that this stuff really works. I bought it in desperation because I was tired of allergies even with shots and pills and sprays! So it’s been about a month and I’m not allergic to my cats anymore, no jokes , they’re not paying me to say this! All the money I’ve spent over the years and all I had to do was get a cat food topper, and a spray, my cats sleep with me every single night! And after I would get my allergy shots, I would get a bad reaction when they would be around me. I feel like I was sick for days two times now I’ve got my allergy shot came home been around my cat and slept with them and I don’t even get a stuffy nose or a headache! Thank you packaging you changed my life!!!
My husband is allergic to cats, and I purchased this to try and see if it helps… and it does!!! He hasn’t had itchy eyes or nose since we started. I’ve very impressed and will be repurchasing!
With this food topper my cats are enjoying their favorite food while it’s helping us with the allergies.
Using topper and spray and allergy symptoms are gone.
