She's a beautiful cat! Her color is either tortoiseshell, or tortie smoke (if her coat is white at the base of each hair), and she would be described as a domestic longhair. Most cats are not any particular breed.
It would be considered a domestic long hair. If I were to make a guess at a lookalike I would lean toward Siberian. It is however a guess.
Gorgeous cat though!
She is gorgeous I love torties, looks like silver smoke in there too... for look a likes I would say some forest cat, the breeds are Siberian, Maine coon and Norwegian forest cat, she looks a bit Persian to me too.
