This Imperial live bate cage simply hangs on the back of our Imperial Pro-50” Folding Trap (as shown) or will also fit Imperial PRO-42" traps. By placing a live animal in the bait cage, it is the ultimate attraction for predatory animals. The bait cage has a easy access trap door on the bottom for loading and unloading the bait cage. All other sides are solid metal allowing sight of the bait animal inside only through the trap. The predator will have to enter the trap to see and try to get the bait animal. The bait animal is 100% safe inside the bait cage. It’s best to hang the bait cage about 6” off the ground on the back of the trap. Once hung use zip ties or wire to secure against the trap. Always use a smelly bait to draw the predator to the trap. Once close, the predator with smell and see the live bait and enter the trap to get the live bait…. Job done! The dimentions of this Live Bait Cage are 20" x 11” x 12"
