My new ball is 141 grams and the first day i got it i put him (or her... don"t know) in a feeding box and put a live mouse in it, it had only been 4 days since the pet store fed it, and it refused, it just tried to climb out of the box. later that night after it settled down in its new home i got him (or her) out and put it in the feeding box, dropped in the mouse and it wasn't 5 mins. before it struck and killed the little guy!!! he (or she) got it down in about 15 mins.. I'm very happy this is my first snake, my buddy brought his baby ball over a couple of times and i just had to have one!!! Hope everyones snakes start eating soon, but it is in there nature to fast while in hibernation, so it may just be doing what comes naturally
