the development of scar tissue is how our bodies respond to a breach in our skin as when your cat's claw pierced the skin of your upper lip. unfortunately scar tissue is not skin tissue and does not look the same or feel the same. with time most scar tissue recedes in size and the pink color will turn more white making it less noticeable. one thing you might try is very gently rubbing a little vitamin e-based oil or cream over the area with the scar to help with the healing process and to diminish the appearance of the scar. if it really is a problem you'll want to talk to a plastic surgeon about your options.
