Thank you jdelano, that's one version. Anyone else like to have a crack at it?

From the graphic below, I was thinking that with the White Mouse in position 1 and the Brown Mice occupying Positions 2 to 13, and starting the victims at Position 2, all is well until day 11 in which our infamous mouse becomes "Main Course of the Day". Position 10 appears to be the best option for the White Mouse.

How do I prove this with vba?
