Hello all my sister has this cat, she says that it is a Maine Coon, and that her vet confirmed it. At first when she was a very little she did look like one but now that her kitten fuzz is starting to fall out she doesn't really resemble one anymore. Could she be a Maine Coon?
Maine Coons are longhaired cats, with a more square muzzle, so I agree with 1CatOverTheLine that she's not a Maine Coon. She's a beautiful blue and white (in the tuxedo pattern) Domestic Shorthair.
