This is the exact trap I used from TSC. http://www.tractorsupply.com/live-animal-traps/live-traps-1-small-size-amp-1-medium-size-5132129 We heard noise at about 1am, went out and saw a trapped racoon. We thought we would deal with it in the morning. In the morning, racoon GONE. Somehow, it had gotten the trap door open just enough. I suspect the "Safety" that is a "New Feature" of this trap. Needless to say, we will make sure that never happens again. But I am SO dissappointed! I ALMOST got him!
