    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.

    Gamechanger

    The allergen neutralizing spray helped calm my boyfriend's SEVERE allergy to my sweet tortie cat. He still gets a bit of an eye itch, but this was after only having the spray for 3 days.
    I'm hoping to try the cat food topper next to help mitigate the allergen at the source (with approval from my vet after a consultation).

    This Actually Works

    I was a skeptic. I have allergies to cats and dust mites - very bad allergies that affect me every day despite 2 types of daily allergy medications. I saw an ad for this and figured why not give it a try. My main allergy isn’t even cats but this worked so well anyway! It’s a total game changer. Then I found the dust mites one and I’m about to order that one since that is my main allergy. I can’t wait to see how that one works too!

    It works

    My daughter is very allergic to cats. She has been on nasal spray and a daily pill and still has a stuffy nose from our pet. This spray is the addition layer she needs to be congestion free and still enjoy our pet!
