It seems that you have linear scar developed after scratching by cat. The scar may be linear and whitish. You may apply hyaluronidase
containg gel or silicone gel. Tacrolimus oint might improve the color. Laser
resurfacing is other option for crrection of linear scar. You may consult dermatologist
or cosmetic surgeon. I hope you got my answer.
