Hello,
I have a colombian boa whose previous owner fed him live rats. So my poor boa has some scars. The scars on his sides are dark in color, and didn't change much after this shed he just went through (the first one since I've had him), so I'm guessing they're older. He has two on his face that seem very new, and I noticed that on his shed skin there's scabs - now the bites are bare skin and white. My question is, do scars eventually fade as they get older? Do they grow their scales back? He's only about a year old (4 ft long, so maybe a little older).
Not that I wouldn't love him any less if his scars were permanent.
