UPDATE

I've had this guy for about a month now, he's eaten twice for me now. He first refused a live rat so I tried F/T a week later, he's been taking them since. He's now at 564 grams.

He had a really odd defecation the first time. It wasn't the normal ball python defecation, it was semi-sold and there was a ball of something... idk. It was the WORST smell I've ever encountered though.. He defecated again yesterday and this time it was normal, he shed too! Snapped some photos of him :].
