We were in a pinch and used this cheapy trap for just one poor little mouse, who was so stressed out that he flopped out, wet, and barely alive. I was shocked and saddened, and threw away the trap immediately. Since then, we went back to the green Smart Mouse Trap, which captures the little guys and isn't too stressful, and then we let them go in the woods. Go with Smart Mouse, they are durable and can be used over and over and over.
