Medical immunologists have long isolated the primary driver of feline allergies: the Fel d 1 protein. This tetrameric secretoglobin, weighing roughly 35 to 38 kilodaltons, is synthesized within feline sebaceous (skin) glands, anal sacs, and salivary ducts. When a cat grooms, it coats its hair shafts in saliva laden with Fel d 1. As the saliva evaporates, the protein dries and attaches to microscopic flakes of dead skin known as dander.

Because dander particles measure under 5 micrometers across, they remain airborne for hours and penetrate deep into human lung pathways. Every cat produces Fel d 1, regardless of coat texture. A cat with ringlets or tight crimps deposits the exact same salivary secretions during daily grooming as a standard domestic shorthair. The biological machinery producing this protein resides inside feline epithelial cells and glands, entirely independent of the hair follicle's physical shape. While low shedding breeds deposit fewer long hairs across household surfaces, the fine skin dust they shed carries enough allergen to provoke moderate to severe immune responses in sensitized individuals.
