Over 30,000 Cat Owners Are Breathing Easier—Here's Why

Michelle

★ ★ ★ ★ ★

"I've tried just about everything - from every allergy medicine out there to HEPA air purifiers in every room and vacuuming religiously. After a particularly bad week with allergies, I bit the bullet and bought Pacagen. And luckily, it worked out very well for me. I particularly love how the product doesn't need to be sprayed on the cat."

Amelia

"I generally don't have cat allergies but my beautiful and sweet long haired cat makes my eyes itch and gives me nasal congestion when she sleeps with me. I tried Pacagen spray in my bedding and now have no issues with kitty joining me in slumber. Thank you!!"

Peter

★ ★ ★ ★ ★

"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."

Katie

★ ★ ★ ★ ★

"My husband began hinting at rehoming or making our cats "fully outdoors," until we got Pacagen. He used to be awake for hours at night unable to breathe and that has now stopped almost ENTIRELY. Pagacen is a little pricey but worth EVERY PENNY. Don't keep suffering, it works!"

FAQs

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, WhiskerBlock is always manufactured to food-grade standards.

WhiskerBlock, being a protein, is by nature subject to degradation when dissolved in tap water, as minerals and impurities can disturb its structure. The Stabilizing Solution is formulated to preserve WhiskerBlock's structure as long as possible without hampering its neutralizing properties.

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 WhiskerBlock is capable of neutralizing up to 98% of Fel d 1. Other products on the market are only able to neutralize up to 50% of Fel d 1. On top of that, our products are incredibly safe to use and are non-invasive to you and your pet’s routine.

While undissolved, the Allergen Neutralizing Powder doesn't expire, but it is most effective within 1 month of dissolving in distilled water. However, if you dissolve the Allergen Neutralizing Powder 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 d 1 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.

For orders within the contiguous United States, we offer 3-day and 5-day shipping options. To Hawaii & Alaska, orders can take up to 8 days to arrive. For orders to Canada, please allow up to 10 days for shipping, as CBSA processing times vary.

Product works as marketed

I've been using pacagen for ~6 months so far and have really enjoyed the product! I have pretty bad cat allergies and have used the food topper daily. Pairing with air purifiers has taken away the majority of my allergies. Definitely recommend the product.

ACTUALLY WORKS!

I’ve struggled with cat allergies for years—constant sneezing, itchy eyes, and feeling like I couldn’t fully enjoy time with my cats. After trying this spray, I noticed a difference almost immediately. My symptoms are so much more manageable now, and I don’t feel the need to run for tissues every few minutes.

What I love most is how easy it is to use. Just a quick spray around the home (especially on soft surfaces where fur lingers), and it keeps the air feeling fresher. I can cuddle my cats without worrying about my allergies flaring up.

If you love cats but hate the allergies that come with them, this spray is absolutely worth it. It’s made such a positive difference in my daily life—I finally get to enjoy my pets stress-free!

Pricey, but it helps

The spray works pretty well. It's not a cure-all but it does help reduce my boyfriend's allergies significantly.

Great Product, steep price tag

The spray itself is a game changer, but pacagen's pricing is sky high. Love the product but we have a tough time justifying the price tag.

It's not perfect either, we're not sure if it's lack of exposure for a certain time period or something else, but my boyfriend still has allergy flare ups sometimes.

I can finally cuddle my cat again!

My allergies were starting to become unbearable. I didn't have high hopes when I got the food topper, I was just wanting to be able to exist in my house again. But since I started using the food topper, I've been able to even cuddle with my kitty without sneezing!
