I'm not sure and would really like to know. I ordered a game camera about an hour ago, so maybe I'll find out sometime next week.
I have two cages, one very large (won't quite fit a deer ) and another med-large (still big enough for a good sized coon). One of the times they stole it, I found the smaller cage flipped over and about 5 feet from where it started, even though it was wedged in between some logs and a rock. The other 3 times, the bait was just gone, including the time I held it in with a stick (which was still in place).
I've tried to set it at the most sensitive, but it seems sometimes they are careful enough. Maybe they are doing it mission impossible style, climbing along the wall...I know there is at least one groundhog out there too (saw him through the window this morning), so maybe he is the crafty one.
