So my 1 year old, 700ish is gram ball python stopped eating about 2 months ago. His temps and cage has not changed since he was eating, nothing changed. I figured since it was winter he is just fasting.

He doesn't appear to be ill, breathing is fine, and when I do go to feed him he has a feeding response where he acts interested, smells the prey, then just ignores it. When he first started fasting, I got him to eat once or twice but nothing recently. I tried switching sources for FT rats and new/old ones don't work. I'm thinking of trying a live rat soon.

I wasn't very worried until a couple days ago, he has started just laying around his cage, his branch, whatever. Took him out last night and he was just super lethargic, not really active. He still had a good grip but I'm getting worried!

Any help?
