Housing for California King Snake

I just changed her tank a few days ago. I use to have the wood chips and just the log. I added the plant with a branch and put down the reptile carpet, she is much more active now with something to crawl around on, but the only thing I need to figure out is what I can use for a hiding spot on the cool side. The last thing I need to know is what is the best way to feed her because I wanna start feeding her in the tank now. I plan to drop the mice in the front, left corner when she isnt looking, would that be ok?
