I've had my Ball Python for 2 years now and he has always been a great eater, are in the winter and always ate dead rats. All of the sudden in November 2013 he just stopped eating, he is 3 years old. He is still drinking water and very active at night. The temps are about 85 daytime and 76 during the night and the humidity is about 50%. I have not noticed weight loss really. Here is a picture and suggestions?
