content: I have caught 7 mice so far in 3 weeks... It's no problem for me to relocate them into the woods with a days ration of peanut butter in their cute little bellies... Mice are very smart and industrious little creatures.... Also, they are inquisitive. They will actually look you in the eyes ! It just doesn't feel right to murder little mouse families for the "crime" of trying to survive... Theyre no different than Dogs,Cats or any other life on earth... I bought 2 of these live traps. I had no problem setting the trip wires. In fact , after a couple of tries it becomes easy. I used a plastic straw to test-trigger my traps by touching the food tray pivot inside the trap... I wanted to make sure the doors would actually close when the food tray was pivoted... I am happy with the product and my Karma is shining happily as well !Havahart 1020 Live Animal Two-Door Mouse Cage Trap
