No no no... you saw my numbers wrong. What I was saying is an item as big around or half AGAIN the girth. 1.5x, which I don't do, means one and a half times the girth - so a snake that is 1" wide would be fed prey that is 2.5".

Half again, using the same 1" width, would be a prey item 1.5".

Sorry to confuse ya.
