I've been feeding mine on a 7 day schedule since i got him 6 weeks ago. He's gone from 105g to 128g before feeding this monday. Also switched from live (his meals before i got him were live), and don't even have to zombie walk anymore (3 feedings now, throw it in, he constricts it instantly, still thinks it's alive i guess...) You guys are making me think i'm doing something wrong.....
