The Myth of the 100% Allergy-Free Cat
It is crucial to understand that no cat is 100% hypoallergenic. People are not allergic to cat hair; they are allergic to the Fel d 1 protein found in cat saliva, urine, and dander (skin flakes). When a cat grooms itself, the saliva dries on the fur and becomes airborne.

Low-Allergen Breeds
Some breeds produce significantly less of the Fel d 1 protein, making them tolerated by allergy sufferers:
- Siberian Cat: Despite their massive, thick coats, Siberians are scientifically proven to produce lower levels of Fel d 1 than almost any other breed.
- Russian Blue: This elegant breed also produces fewer allergens and has a dense double coat that traps allergens close to the skin instead of shedding them.
- Devon Rex & Cornish Rex: These breeds have minimal, curly coats that shed very little, meaning less allergen-coated hair floats around your home.
- Sphynx: While they still produce dander, their lack of shedding hair means allergens are not spread around the house as easily.
