Messy Regions

The combination of region borders and cages creates a confusing grid--but the clues are necessary. The yellow scattered cells are colored for clarity. When solving, I always color the irregular regions, but I left them uncolored so you can choose your palette.

 

There are nine irregular regions in this puzzle (eight connected regions, and one yellow scattered region).

Place the digits 1-9 once in every row, column, and irregular region.

Digits do not repeat in a cage and sum to the number given.

The nine cages correspond to the nine normal 3x3 boxes. Each cage contains every unique digit in that box.
