This trap was catching large rats that were digging into the compost bin. It looks like it took three smaller mice to trip the same trap. Sometimes it doesn’t pay to share, since if only one mouse had eaten at a time, it probably wouldn’t have had enough pressure to trip the trap. If you look toward the right, you can see where I’ve put wire mesh under the compost bin so rodents won’t be digging into it from the bottom in the future.
