What kind of breed is my cat?

He's very playful, very friendly with human but my other cats doesnt really like him because he's kinda rough when playing with others..his weight is 6kg.. He's also a very active cat..

Do you know how his mom, dad, littermates look?   Your other cats arent his relatives, no?

Anyway, pattern-wise he is a ticked tabby with white.   You could probably say ticked tabby tuxedo.

He has no stripes anything on his back - this is why ticked.  Not so common, although its a rather dominat gene.
