Rainbow is my new SunTiger female reticulated python progression.

Ok, I kinda figured, but figured it couldn't hurt to ask.
My best guess (although I don't have retic experience) is she's simply not hungry yet. A lump that large, and still noticeable 4 days later should be enough to sustain the snake for longer than 14 days.
I'd just wait her out. Also, offering multiple prey items over 4 hours could be more of a hindrance than help.

Yeah, not freaked out. She is healthy. She will get hungry again eventually. At almost 11 feet now she might also be slowing down growing also. 22 lbs was her last recorded weight. Just documenting her progress and eating habits. Trust me, when she is hungry you know! LOL.
