I have a 3 year old corn snake that is 43 inches long. Up until 4 weeks ago he was eating a mouse every 7-10 days for the last two years. now he wont eat! I have offered a mouse every 7 days, with exactly the same conditions, but he just curls up as far away from the mouse as he can get in his eating box.( thawed mouse). I am at a loss as to what to do. He seems other wise healthy, he shed about 3 weeks ago. Still sticks his head out when you walk in the room. Any thought would be greatly appreciated.
