Great news!!!

Put a sock on her hind leg... It'll be really uncomfy for her, but it'll help stop the scratching, as her paw will feel too weird to scratch, or it'll atleast add some padding to those sharp claws.

I used a dog booty when Cadeau had some fatty lumps removed.. she hated the booty & her scratching went down by more then 50% as sge hated the feel of the boot.. + the boot is thich & her claws couldn't hurt her, so when she did scratch, it wasn't too much of a big deal
