A Killer Cage/Dutch Whispers sudoku variant

Normal sudoku rules apply, (fill each row, column, and 3x3 box with the digits 1-9 once each).

Digits in cages cannot repeat within their cage and sum to the total given in the top left corner of the cage.

Additionally, orthogonally adjacent digits within the same cage must differ by at least 4.
