I'm at my wits end.
I know balls go off feed periodically. I know they are picky eaters. I know all these things. But it still worries me.

Nico, my 1.5 year old, hasn't eaten since 10/28, and then it was only 1 good sized adult mouse.

I moved him into my rack system about 2 weeks ago, thinking maybe better regulated temps and humidity would help. He's seemingly content. He hasn't lost any weight [he's not defecated since then either]. He still looks good body wise. He's not sick. For all intents and purposes, he's a healthy happy ball python.

But he won't eat. I put him in the feeder cage, and he explores it, sometimes coming nose to nose with the live mouse, and still does nothing. [I of course monitor for possible scuffles].

I just...don't know what to do. Should I worry, if he's not losing weight and still looks healthy? Or do I need to start being concerned?
