Rat munched on the snake

[Slinky2]

My 🐍 snake & I live in frozen NORTH. DAKOTA!!
. We haven't had the best of times lately. As you can guess it's COLD up here and as we all know, my serpent friend is not meant to be in such a unfriendly climate... Well to make. Long story short, she froze. I got my power cut & couldn't get to her in time. I and everyone else really thought she was dead. But I remembered that she was probably in. State of hibernation /shock. Well after about 3-4 hrs, she was showing signs of life) I think she's ok. But... I thought MAYBE she would eat a small rat even tho she was trying to shed in. Not.! .. I made the mistake of leaving her unattended w said rat for too long. The rat had taken about an inch off the tip of her tail. . What to do? What will happen? [should she b seen by the vet?? Please she's about a 690 1
