Rick--yes, I did continue to monitor it. It was in the Fall of the year. I thought that maybe they were squirreling away a winter food supply so I left their depository totally undisturbed. The following Spring I uncovered it and found the entire mass partially to completely decomposed (no longer in much pellet form). None of it appeared to have been eaten. At the same time, I was able to see and determine that the delivery tunnel had been solidly sealed off with dirt from the main route for about 12 inches. While the voles continued to work the area under the snow that winter, they avoided this spot. So, what can we conclude? My theory was that these little guys are so smart, they somehow recognized the pellets as something that made them sick and so to avoid any accidental consumption, especially by the very young, they moved all of it to a safe place of no risk. What do you make if it?
