I got jimmy from pet smart in October 2015. Ever since I got him he has bee eating 3 mice every Monday like clockwork. I have had no issues with him eating. Where I live there is only one place to get live mice or rats, and he is still to small to eat the smallest rats they have. He has went thru shed twice since getting him. All of his temps are on point, humidity is great, he enjoys his warm side hide and does not use his cool side hide, opting to lay in the back corner of the tank behind a log and some plants. He is well behaved has given me no problems with handling him. On dec 7th he ate all 3 mice then I noticed he was acting more shy than normal, so I figured he was going into shed. On the 14th he only ate one mouse, then on the 20th I woke to find he has shed fully in one piece. On the 21st he only ate one mouse. The 28th was his first vet visit, he weighs 325g, she estimated him to be around 6 months old. That night he wouldn't eat and has not ate since then. I have offered him 2 different mice couple times a week with no luck. Sometimes he will follow them around and act as if he is interested, but nothing happens. I know that bp are known to fast in the winter and I have moved North where it is pretty cold and my inside temp is normally cool. I just worry about him not eating. I am from the south where we feed everybody and everything. Is there anything I can do , and when should I start worrying?
