Erica 19 (German Whisper Yarn Edition)

Today we have Erica created for Scojo's prompt with cats and something similar to marty_sear's Rat Run series :-)
I hope you will enjoy and I would be really grateful for all the comments and ratings.

Normal sudoku rules apply.

Leo's Path: Help Leo the puss to nudge his German Whisper Yarn to his friend Kitty. Draw a one-cell wide orthogonally connected path which starts in R9C9 and ends in R5C5. The path can touch itself orthogonally and diagonally, but cannot branch, cross itself, or visit any 3x3 box more than once. Also, it cannot visit any killer cage. Additionally, the path acts as a German whisper line. It must go through every X in the grid, and must visit exactly 1 of 2 cells joined by every V in the grid.

German whisper: Neighbouring/adjacent digits along a green line have a difference of at least 5.

X/V: Digits in cells joined by an X sum to 10. Digits in cells joined by a V sum to 5. Not all Xs and Vs are given.

Killer: Digits in a cage may not repeat and sum to the total if given.

I'll give it a spicy 2* but probably not a full 3*

Either way, excellent puzzle. Thanks
