Not Siamese- they are shorthaired cats. Balinese are longhaired Siamese, but I think even an old style Balinese would have a more slender body. My guess would be that your handsome Marley is a nice lookalike to a pointed Siberian. Without having papers or a DNA test, it’s impossible to prove if he actually has Siberian influence, so he’d be called a flame point Domestic Longhair.
I was thinking birman. my profile pic is a siberian. she's got those round siberian eyes but the facial structure looks different than siberian to my eye.
