Hypoallergenic cat breeds include Cornish Rex, Balinese and Sphynx. Cornish Rex cats have characteristic wavy hair. Although the Balinese breed has a medium-length silken coat and a fluffy tail, it sheds very little. The Sphynx breed has prominent wrinkles and most are hairless, but some are covered in delicate fuzz.
Hypoallergenic cats produce less dander than other breeds. Although cat dander has been shown to cause allergic reactions in some people, a protein called Fel d 1, which exists in the saliva of cats, may be the actual offender. The saliva of Siberian and Balinese breeds have a smaller amount of this protein.
