Your beautiful cat in the pictures (long soft fur, round wide eyes, and a cute full face) belongs to the Persian Cat breed, specifically the Doll Face Persian type, also known as the traditional Persian with soft features and a slightly prominent nose compared to the Flat-Faced (Peke-face) type. It also appears from the color of its fur, which is white tending towards very light cream (Cream or Off-white), playing on calm golden tones.
