The culvert above was plugged wtih a mud dam.  Mud dams are conducive to using The Comstock Beaver Cages, which can be placed in front of the dam with a small trickle of water passing through the trap.  Even a small leak in the dam will attract a beaver.   The traps are set in single door mode, upside down, with the upper end of the cage resting against the dam.  It is the closed door, of course, that is again the dam.  The lower end of the trap with the opened door is placed towards the pond, resting just below the surface.  Road fabric is used to cover the entire cage, even past the closed door right up to the dam.  Loose muck is then packed on top of the cage to conceal all of the fabric.  The trap will lie at a slight angle, raised perhaps a couple of inches at the closed door, leaving an air space. 

This shows a set and cage buried into the dam, totally invisible to passers by. 

Not only are the traps invisible, but better yet, the catch is too.
Pulling the fabric back reveals a small beaver in the cage.

A New Setup.  Feral Cat Capture in the newest Comstock 10x8x36 panel trigger trap.

Had a trapper take a bunch of feral cats in pan traps, but one was too smart for the pan.  He probably had been caught before and would actually sleep inside of the trap.

The new Comstock traps have a panel trigger that works like the wire trigger cages, same principle.  The trapper in this case tried something innovative and new.  Instead of using the trigger in the intended manner as a push through trigger, he clipped the panel back and used a stick as the trigger to replace the panel.  By propping a stick up under the trip rod part of the trap, the door was held open.  He then put some of the new Gary Jepson Cat Rub lure on the stick.  The cat walked into the cage, brushed up against the stick as you would expect and was caught first night!
