A cat breed is an infrasubspecific rank for the classification of domestic
cats. A cat is considered to be of a certain cat breed if it is true breeding f or the traits that define that breed. Various cat registries around the world record and certify the pedigrees. Only three percent of owned cats belong to a cat breed, and an even smaller percentage of those are suitable as show cats. A registration certificate proves that a cat belongs to a cat breed by showing the ca t’s pedigree back to at least four generations. The whole concept of cat breeds is a relatively new one. Two hundred years ago there was no such thing, however today there ar e almost one hundred cat breeds. Varieties of domestic cat can also be identifie d by characteristics other than breed.
