Cat Allergen Management

Managing Cat Allergens

Allergies to cats affect as many as 1 in 5 adults worldwide, and human allergists typically recommend avoiding cats to reduce allergen exposure.1 However, most cat owners consider their pets as part of the family, and often resist removing the cat from the home. A novel nutritional approach can help neutralize the major cat allergen (Fel d 1) in cats’ saliva, before Fel d 1 spreads to the environment. As part of a comprehensive cat allergen management program, this new approach provides an opportunity to reframe conversations with pet owners: it can help reduce exposure to the allergen – not to the cat.

Contrary to popular belief, it is not the cat’s hair that causes a reaction in sensitized individuals. Allergens produced primarily in cats’ salivary and sebaceous glands are responsible for triggering a reaction. This means that even hairless cats, like the Cornish Rex and Sphinx, produce this allergen.2

Key Messages

  • 95% of people who have sensitivities to cat allergens are responding to Fel d 1, the major cat allergen.2 
    • Fel d 1 is produced primarily in the salivary and sebaceous glands, spread throughout the cat’s hair during grooming, and then shed into the environment with hair and dander (dead skin cells). 
  • Cat allergens have consequences for both the allergen-sensitive owner and the cat.
    • Limiting interactions between owners and their cats in efforts to avoid or reduce allergen exposure can cause anxiety and stress for the cat.3,4
    • Allergies are one of the top reasons for relinquishment of cats to shelters.5-8
  • A nutritional approach can safely help reduce active Fel d 1 on the cat, before the allergen gets into the environment.9-11 
    • Published studies show that when cats eat kibble coated with an egg product containing antibodies to Fel d 1, this ingredient can bind to the allergen in the cat’s saliva and neutralize the allergen. This neutralized Fel d 1 is distributed through grooming and shed into the environment, but is not recognized as an allergen by a sensitized individual’s immune system.
      • 47% reduction, on average, of active  Fel d 1 on cat’s hair beginning with the third week of feeding the diet.
      • 97% of cats showed decreased levels of active  Fel d 1 on the hair and dander.
    • This approach maintains normal allergen production by the cat, without affecting the cat’s overall physiology.

"Most people who are ‘allergic to cats’ are actually sensitized to a specific protein, called Fel d 1, found in cats’ saliva and on their hair coat. To avoid these allergens, human allergists recommend removing cats from the home. But a nutritional approach can help reduce active Fel d 1 on your cat so you can reduce allergen exposure and still keep your cat."
