Last night at 1AM my dog kindly let me, and the rest of the neighborhood, know that one of my rat traps caught something. I went out this morning to dispose of the evidence and was rewarded with the largest rat I've personally ever seen that was still, after 4 hours in the trap, still very much alive and kicking. I shot it 4 more times with my .177 before it finally quit thrashing. Tough buggers.
