I wonder if any one could give some advice, we have 5 hedgehogs visit us each night, one of the hedgehogs is a good size and was around last year, last year and this I have noticed a white mark on its back end, the mark is horseshoe in shape and size, the trail cam which is set up makes it very noticeable, looked close at the video and their seems to be no spines missing or damaged, not sure if the trail cam is making it stand out more than usual, very doubtful if it has been deliberately marked, the patch is more noticeable than last year but not significantly worse., all the other hedgehogs are fine in appearance. Any advice would be appreciated if you have come across this before, Thanks Gary
