Has anyone had any success restoring their leather sofas from cat scratches?
I've looked up the kits on Amazon and watched some Youtube videos but I'm not convinced I'd be able to recreate the results.
The sofas are tan, matt (nubuck?) leather. The damage is in specific areas such as the sides/ back and particularly the front at floor level where the monster has hauled himself along on his back 
The damage is lots of fairly deep plucks where he's been gleefully sharpening his claws. No long scratches or threads. He's now banned from the living room since I discovered the extent of the damage.
In honesty I'm not expecting miracles but it would be nice to remove some of the more visible damage to the sides and front (the back is against the wall).
ps I love him really. He's allowed in the living room under close supervision! He has the run of the rest of the house which he somehow manages not to shred
