Boy I love putting trail cams on my traps when testing lol, always learn something new. Anyway I've always made my cages out of 2"x4x 10ga horse pannel. Personally I prefer cutting and welding together panels then dealing with bending and hog ringing 14ga wire. Super easy to weld in my trigger rods and mechanisms as well.Not to mention the crap is about bullet proof. Heck I had one fall out the bed of the truck doing down the road goin 55 one day. Picked it up dusted it off and was good to go. Only deal is small critters like civiet skunks , squirrels, pack rats can get in and out and not be held ,but honestly I could care less about them because most of the time I'm after coon possum ,striped skunks grey fox ect so I've never really had problems with holding them. Can't tell you how many possums I've held in these cages over the last few years . But lately I've been build double door traps to be used in trails and the like . Just plop it in blend it a little critter tries to walk though hits a wire trigger or pan and boom caught. Deal is I've been having more triggered traps with no catch in these then anything elese which I though was weird because with the single doors it it was down 9/10 times there was a catch. Well stared running cameras on my latest one and caught a door drop and escape all in one ! Honestly was just thinking the traps where too short and they where hitting critters on the back and letting them back out or it was squirrels but nope, apparently an average sized possum ! And again I've caught and held ALOT OF THEM. Actually have close two three hours of footage of one trying to get out of another cage till it jaut gave up and went to sleep. I honestly had no clue they where like rats in the fact if they can get their head though they can get their whole body. Raised a few and never saw this but idk many this one is special ?
