Step 3: Set That Trap!

Just follow the imiges.

3 Close up of the knot on the connector
4 The carrot
5 The carrot on the string
6 The string goes over the big wheel.....
7 Then over the small wheel......
8 And through the orange and on to the red rod. Note that the round end to the rod should be in the groove of the red rod.
9 Set trap

Step 4: Finished!

Your done! just set it on the ground and you'll have a caught guinea pig relatively soon!

If you haven't already realized how it works, here's a quick description.

The guinea pig goes in the trap to get the food. Then it will grab it, and try to bring it down to ground level. In doing this, it pulls the string, which in turn pulls the pin out of the way of the door, which then slides down behind the guinea pig. And voila! you have a caught piggy.

    Perhaps... They are much cleverer than guinea pigs I think, though.

    Really? I might have to try that one.

    ( I'm SUPER bored) Yep, though you'll need sometime of device that tells you when their caught, so they don't chew their way out. :-P

    Yes. They seem like they would do that.

    HAHAHA I have a CAT named DeeDee!
