not sure who else feeds live, like I do, but when you do, always monitor what is going on. I always have something long and thin to block the rat if it has a chance of biting my snake(s). I watch until I know the rat is passed. Then I close the bin. If the snake has full control of the rat from the strike, I make sure it's locked on, then again, close the bin. I also watch for back feet scrapping against the snake. I've learned once, as the rat was a medium-large size, and they are indeed to dangerous. Which is why I am only feeding large weaned (40-50 gram) rats. Safer, and easier to control if the snake has a chance of being bitten.
It appears it was your first attempt at live. So, please do what everyone is asking you, take it to the vet. If indeed the snake survives from it's injuries, and you are only able to feed live, monitor your feeding, and use something to assist with possible biting next time.
This is a very hard lesson to learn. But, do all of good, and help this snake.
Also, don't be afraid to come back and let us know the progress.
