Ball Python Hasn't eaten since November?!?!

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?

Fairly normal. As long as he maintains a healthy weight you should be fine. Keep on trying offering. You could also try ASF or live rodents but he may get hooked on them!

Yeup, relatively normal. I have one that hasn't eaten since October 2013. You could try bumping up the heat a couple degrees too. That may get him going. Either way, he'll come out of it. Keep offering like ridin said.

Ok, thanks guys!

My adult male went off food 10/8/13 and started eating again ten days ago.

Personally I wouldn't do the night drop and I would keep him warmer, at 78*F cool side and 90*F warm side all the time.

Yup, normal. Not all do it but a lot do. And how the little buggers knkw its breeding season in a stable artificial environment is kinda nuts.

Perfectly normal. He's an adult male and it is breeding season. But, I agree with others, no need for the night drop. I don't even do it for my breeders anymore.

Throw in a live mouse !

I wouldn't worry. Before he stopped eating did he happen to hit around 1000g? All 3 of mine were fantastic eaters until they hit that weight, regardless of age.

when they hit sexual maturity they will sometimes stop eating for a bit. Around 3 for males. Get a postal scale, log his weight. As long as his not losing a lot of weight he's ok.
