I have a quick question about scars and scales for a first time snake owner.

Marley suffered from an attack a few months ago in late summer by a kitty (mine, crazy thing has it out for reptiles) and I had no problems treating the wounds and cleaning them and they all healed up nicely but a few of them are missing scales.

Now will those scales regrow over time or is it only going to be the scar tissue in its place. My only experience is with lizards that can at least regrow tails so I'm new to this.

None of the scars are big ones so if they don't then I'm not too worried, I'm more or less just curious.
