Not really but I sure did see and hear one. I was sitting in the kitchen reading a book last night when a rat scrambled down the aluminum ladder that accesses upstairs. He ran into the pantry and I think he was hiding in some rubber floor mats that are leaning up against the doorway. I gave the mats a big kick and he scampered across the floor toward some shelving I built for storage and disappeared behind it. I heard noises from behind an old refrigerator sitting in the corner to I went to investigate.
Before going over, I grabbed my air pistol and a flash light. I looked behind the reefer and saw him hiding in the gas hoses behind it. I couldn't get a clear shot, and didn't want to damage the hoses, so I rattled the hoses with my foot. He ran around to the side of the reefer between its side and the wall. I think he thought he was hidden but I saw him. I cocked the pistol and took careful aim and then BANG, the rat was no more.
Some might think this a cruel thing to do to a rat, but I think it is just as humane as using one of those "neck-breaker" traps or even a live trap which doesn't harm the rat until the next morning when you drown it.
