I had a problem with my neighbors cat getting into my garden beds and doing its business. I set several mouse traps in the cats favorite spot and after a few days the cat decided to move along. I actually watched as the cat squatted over one of the traps and when the pooper landed on it the trap went off. The look of initial confusion was priceless. The cat was no worse for the wear = it had already been fixed. Better than shooting it.
