    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.

    We carry a lightly fragranced (Floral Breeze) and a fragrance-free (Natural) version of the spray. The Floral Breeze scent is very mild and most customers report that the scent is close to unnoticeable after spraying. The fragrance-free formula was developed for those who are extremely sensitive to specific scents (i.e., Morning Glory Scent and English Lavender Scent).

    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.

    Lulu Approves

    Lulu, my rescue from the Humane Society, did not know that some people are a little allergic to her. She is not allergic to anyone, so she cannot understand why some people come over to glance at her and only comment "Oh, isn't she cute.", but no pets!
    To everyone's amazement, Pacagen woked immediately, and even most allergic were able to pick her up. Lulu merely purred and said "of course, this is the way it should be."

    Significantly reduced my boyfriend's cat allergies

    My boyfriend has moderate cat allergies and Pacagen has been a big help in reducing his allergy symptoms. The only complaint I have so far is the price. It's very expensive, and that cost obviously adds up since you need to consistently spray 2-3 times I week. I find that it costs me about $190/month to keep up with Pacagen.

    Greatest product ever!

    I've had cats just about all of my 64 years and have never been allergic until the past 2-3 years. I love my 3 babies and can't bear to think of having to surrender them. So, i saw a pacagen ad and decided to try it. Wow, what a difference! About every week to 10 days, I lightly mist every chair, carpeting, cat beds and condos, and in the air of every room with pacagen, and no more itching, scratching or watery eyes the very first time i tried it in july 2024. Great product! I highly recommend it!

    Game changer

    I’ve struggled with cat allergies for several months now - constant sneezing, itchy eyes, and needing to keep my distance from my own pets. I wasn’t expecting much when I tried it, but honestly, it’s been a game changer.

    The spray itself feels fresh and light — no strong odor or residue — and it’s incredibly easy to use. I’m now able to cuddle with my cat without the usual allergy flare-ups. It’s such a relief.
