Okay, my ball python is 2 years old, and he did go off feed last winter for about 3 months, but he was eating by this time last year. We are having a colder winter than last here in Northern CA, which might make a difference anyhow. He went off feed from October to Dec, ate 2 meals, then decided no more ever since. I've tried rats of different sizes, colors, dead and alive, I've tried different times of day and night, tried putting him in a plastic box with it. I keep him humid enough and his temps are pretty good.

He's lost a noticeable amount of weight, but is healthy otherwise. When should I be worried? Any other creative feeding ideas are welcome.
