I can't kill a mouse, and as much as I hated to destroy the fun our cat was having at night in the basement (and she brought a live one upstairs for my wife and me to enjoy!) I wanted to have them OUT of the house but very much alive. These traps did an amazing job! Easy to use, clean and neat and they don't hurt the mouse. (Please remember to check them each day so the poor little creatures won't starve.) Highly recommended for us soft hearted (soft headed?) animal lovers. These traps are reuseable, easy to clean and much smaller than suggested in the picture in the listing. Most importantly, they are humane...and they really work!!!
