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.
