Feeding help

I fed my kingsnake a meal that was too big for her. When I picked the mouse I forgot how small she was. I put the mouse in the cage, saw that it was quite big, but before I could take it out she snatched it up and wrapped it. I tried to get it from her, but to no avail. It took her about 15 minutes to get it down, but she did it. My question is, should I be concerned? I was going to add a light to her cage to up the heat a bit to help her digest, but is there anything else I should do? Here are a couple pictures of her after eating the mouse. Am I being a worry-wart? She's my first king and I enjoy her immensely and don't want to cause a problem with her. Any suggestions or advice that would put my mind at ease would really be appreciated. Thanks

Kings are extremely hardy snakes. In the wild they will eat just about anything they can swallow. I wouldn't worry. The only danger to be thinking about in the future is that feeding live mice to a smaller snake can, but rarely, cause injury to the snake. But in this case, your snake should be fine. The fact that it went at a mouse that was larger than normal might be a sign that she is quite healthy, having the energy to take down such a large prey item!
