Reduce cat allergens

Just because you are sensitised to cat allergens, doesn't mean you have to miss out on having snuggles with your favourite feline. If you're the 1 in 5 people globally who are sensitised to cat allergens, you will be well versed in how to manage it. Lots of cleaning and creating cat-free spaces in your home. Now, there is a scientific breakthrough (more than 10 years in the making!) to provide an additional measure to help manage the cat allergen burden within the home.

What causes cat allergies?

Allergens in cat hair and dander can greatly affect the lives of cats and their owners. Are you one of them? Most people think that these sensitivities to cat allergens are caused by cat hair, but that is not true. This is actually caused by an allergen called Fel d 1, found in cats' saliva. When cats groom themselves, they spread the saliva onto their hair, and shed the hair and dander into the environment, leaving a trail of allergens throughout the home.
