Thankfully your snake is alright. This could have been a whole lot worse. My friendly advice to you (and please don't take this personally) is to try and switch your snake to either frozen thawed or pre killed rats/mice . Or if it's a live and only live feeder keep an eye on it while it's eating and have a pair of tongs or something that you can stick in the rats/mouse mouth while your snake is constricting it... This can help avoid situations where your snake can get tagged... Best of luck with your snake.
