I have a big problem. My California Kingsnake doesn't seem to feed. Got the snake just three weeks ago from a friend who is giving up his hobby. He told me that it feeds on both live mouse and hamsters and it does look quite healthy. However, it just feeds on 1 mouse on the first week and started to crawl about in its cage. Seems like trying to find a way to escape. On the second week, I gave it another mouse. It showed no interest in the mouse. Then I toke out the mouse and put in a hamster. It tried to constrict the hamster three times then releases it just before it is about to die. On the third week, tried giving it a mouse. It kills the mouse and just leave it in its cage, simply ignoring it. Please help me. I have no idea what I should do.
