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.

Purina Impact Of Cat Allergens
As many as 1 in 5 adults worldwide are sensitized to cat allergens.
Purina Impact Of Cat Allergens
Avoiding cats or relocating them to other homes is a common recommendation for controlling allergens in cats.
Purina What are Cat Allergens?
What are Cat Allergens?
Although many people believe cat allergens stem from the cat’s hair or dander, the major cat allergen is Fel d1. This protein is found primarily in the cat’s saliva.

Fel d1 is then transferred to the cat’s hair and skin during grooming. As the cat sheds, the allergen on the hair is dispersed throughout the home.
Purina What about Hypoallergenic Cats?
What about Hypoallergenic Cats?
Contrary to popular belief, there are no truly hypoallergenic cats. All cats—even hairless ones—produce Fel d 1, regardless of breed, age, sex or neuter status.

Additionally, Fel d 1 levels are not affected by hair color or length.

Fel d 1: The Major Cat Allergen

A protein produced in a cat’s salivary and sebaceous (skin) glands. Transferred to cat’s hair and skin during grooming. Dispersed in the environment via hair and dander (dried flakes of skin).

A Revolutionary, Feline-Friendly Way To Manage Cat Allergens

Purina A Revolutionary, Feline-Friendly Way To Manage Cat Allergens

After more than a decade of research, Purina scientists discovered  cat allergens are reduced when cats eat a diet containing an egg product ingredient with antibodies. These antibodies specifically bind and block Fel d 1 in cats’ saliva.


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 beginning with the third week of feeding the diet.


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


Our discovery has the potential to transform how people manage cat allergens.
