Is it a cat? Is it a fox? Is it a mouse? Is it a new animal yet to be discovered and named? I don't know, but it is abominable nonetheless!

RULES

Normal Sudoku rules apply.

• German Whisper: Adjacent digits on a green line differ by at least 5.

• Region Sum Lines: Box borders divide blue lines into segments. Each segment has the same sum. Different lines may have different sums.

• Renban: Digits on a magenta line form a non-repeating consecutive set in any order.

• Kropki: Digits either side of a white dot are consecutive. Digits either side of a black dot are in a 1:2 ratio (one is double the other)
