What does it do?

Graphic depicting cats secreting an allergen called Fel D1

Cats produce a protein called Fel D1, the main allergen causing cat allergies. Our Starter Pack is specifically engineered to target and neutralize these allergens.

Graphic depicting Fel D1 neutralizing nanobodies contained in Pacagen's Neutralizing Powder

This is done through the use of specialized proteins called nanobodies. These nanobodies are the main component of the Neutralizing Powder.

By dissolving our Neutralizing Powder in Stabilizing Solution, the nanobodies become activated. Now, simply spray the mixture on surfaces or in the air, and neutralize up to 98% of cat allergens!

Carefully formulated to be safe for you and your pets.



Brings the latest advancements in biotechnology to your home.


The nanobodies neutralize up to 98% of airborne allergens.


99% of the powder and 100% of the Stabilizing Solution is biodegradable.


1. Every pack of Allergen Neutralizing Powder is formulated to be dissolved in one bottle of Stabilizing Solution so you don’t have to do any measuring! Mix the two together thoroughly, making sure that the powder is entirely dissolved.

2. Spray the mixture around areas your cat has been, both in the air and on surfaces your cat enjoys being on. Don’t worry, the spray is not harmful to you or your cat! Avoid spraying the mixture directly onto your cat, cats generally don’t like being wet.

3. You should feel symptomatic relief soon after spraying. Depending on the concentration of your cat’s allergens, spray anywhere from twice daily to once every 2-3 days. If you still experience allergy symptoms after a week of regular spraying, try increasing the spraying frequency. If your symptoms persist even after increasing the spraying frequency, reach out to our customer support team!

Definitely! We made sure to use a completely pet-friendly approach when creating our formulas. Each part of the formula was hand-picked to be safe for everyone, four-legged or not, involved. However, it’s best to avoid spraying directly onto cats – mainly because cats usually don’t like getting wet. On top of that, the allergen-neutralizing nanobodies are always manufactured to food-grade standards.

For your peace of mind, here's a full list of ingredients:

  • Nanobodies
  • Sodium Chloride
  • Glycine
  • Leucine
  • Morning Glory Scent
  • English Lavender Scent
  • Sodium Benzoate
  • Potassium Sorbate
  • Silica

The nanobodies are proteins, so they are subject to degradation when dissolved in tap water, as minerals and impurities can disturb the nanobodies’ structure. The Stabilizing Solution is formulated to preserve the nanobodies’ structure as long as possible without hampering its neutralizing properties.

You can find a full ingredient list below:

  • Distilled water
  • Glycerol
  • Ethylhexylglycerin
  • Phenoxyethanol
  • Sodium Chloride
  • Glycine
  • Leucine
  • Acetic acid buffer (at pH 5.7)

Our products use the latest developments in biotechnology to provide you with a safe, pure, and environmentally friendly solution to your allergies. Internal testing found that our nanobodies are capable of neutralizing up to 98% of Fel D1. Other products on the market are only able to neutralize up to 50% of Fel D1. On top of that, our products are incredibly safe to use and are non-invasive to you and your pet’s routine.

The nanobodies don't expire, but they are most effective within 1 month of dissolving in distilled water. However, if you dissolve the nanobodies in our Stabilizing Solution, it'll be effective for up to 2 months.

Spraying frequency depends on a lot of factors, including how much Fel D1 your cat produces, how severe your allergies are, and how sensitized your immune system is. We recommend starting out by spraying once every 2 days, then increasing or decreasing the frequency depending on if your symptoms are still present.

We take pride in the fact that our sprays are designed with environmental consciousness in mind. Where possible, we use biological ingredients that have no long-term environmental impact. In fact, 99% of the ingredients in the powder are biodegradable! We also make sure that all of our partners share a similar commitment to environmental consciousness.

Right now, we are only able to ship to the United States and Canada (excluding Quebec).

For orders within the United States, we offer 3-Day and 5-Day shipping options.

Orders to Canada will arrive within 12 days.

Purchased it for friends with cat allergies, and it's been smooth sailing. Simple to use, highly recommend since it eliminates the need for pills.

My girlfriend has severe allergies to cat hair (sneezing, running nose). The Pacagen spray actually works pretty well for her and along with some allergy relief pills, she’s completely okay to stay with our cat for a long time. Works great so far since I started using one month ago, hope it will be effectively in the long run too!

A miracle cure to my cat allergies. Was never able to visit with my son & daughter-in-law who have two cats. Even with Zyrtec and Flonase I got itchy puffy eyes and face that lasted a day or two. With the addition of Pacagen, I was not only able to visit, but I actually slept in their home for 2 days/nights.

We do A LOT to mitigate cat dander—liveclear allergy food, HEPA air cleaners & vacuums, regular brushing, routine laundry, etc.—but I am always still suffering. [...] But bottom line is that I have noticed a significant reduction in my allergies since using this product.

I just got my first cat a few weeks ago. I was taking 2-3 allergy pills a day. Now after this product I'm taking 2-3 a week. It seems to be helping a ton. It is definitely worth a try if you experience allergies.

Would buy again

Pacagen's cat allergy spray has been a pleasant surprise. Many products over-promise, but this one seems to work. My girlfriend usually struggles with cat allergies, but this spray has made a noticeable difference.

Seems to be working!

My boyfriend is mildly allergic to cats (gets itchy eyes and stuffed nose) and we are starting to live together but I have a cat and did not want him to be miserable so I bought this spray to test if it helped. I used it every day for two weeks while I was there and he didn’t have a single symptom!

Miracle spray

Genuinely shocked by how well this works. My eyes don't itch, I sneeze 50% less, and my mom doesn't get a headache when she walks into my apartment.

Worked great to address my husband's allergies

I used this in conjunction with a deep clean and putting an air purifier in our bedroom while my husband was away. When he returned his allergies were so much better, and we no longer had to keep our 2 new kittens out of the bedroom! It has been almost a month now and he is still doing great. I spray this daily in our bedroom after making the bed.

Magic in a spray bottle

I have finally met a wonderful, amazing man!! But, he is severely allergic to my cat. I felt an unthinkable decision looming either way it went. I literally laughed out loud when I saw Pacagen on Facebook, but I'd tried everything else, so feeling like a fool, I ordered. I sprayed the stuff everywhere, laughing the whole time. My boyfriend was able to spend a weekend at my house, with just a sniffle or two!!!! WHAT??? Because of Pacagen, I have my kitty AND my man!!!!
