A major breakthrough in managing cat allergens

Purina scientists have found a way to safely reduce active levels of the major cat allergen found in cats’ saliva. This can transform the way people manage cat allergens. Rather than limiting their exposure to the cat, they can limit their exposure to the allergen instead.

Impact of cat allergens


Many people go to great lengths to reduce allergens in their environment, such as daily cleaning and frequent washing. Cat allergens can limit people’s interactions with cats, though, and they’re a common reason people relinquish cats to shelters. Allergens also create a barrier to cat adoption and ownership.

A revolutionary, feline-friendly way to manage cat allergens

After more than 10 years of research, Purina scientists discovered the primary cat allergen can be reduced when cats eat a diet containing a specific protein found in eggs. This protein safely binds and blocks Fel d 1 in cats’ saliva and this inactive Fel d 1 gets transferred to the hair when grooming. This is a safe, feline-friendly approach and does not interfere with with Fel d 1 production or change the cats’ overall physiology.

According to a landmark Purina study

Of cats fed this egg ingredient, 97% showed decreased levels of active Fel d 1 on their hair and dander.

On average, there was a 47% reduction of active Fel d 1 on cats’ hair, starting in the third week of daily feeling.

The decrease in active Fel d 1 on cats’ hair and dander can help reduce cat allergens shed into the environment.
