It can be done, haha! This was from a muskrat job I did last summer on two VERY small ponds for a retirement community. I pulled on the chain and thought I was going to be pulling out a rat but it wouldn't budge. Therefore I grabbed the trowel and started poking around. After a few snaps on the trowel, I knew what I was dealing with. I learned two lesson from this job, always pack a shovel and don't under estimate the catch potential. I trapped 10 rats and of course 1 large snapper. Oh, and another lesson, the potential for extra pay. I almost doubled my take home pay by filling every hole those rats made.
