I've had a mouse caught in 1/2X1/2 wire where it couldn't go in or out so me being me rescued it and set it free on my way to school.Now where it gets interesting I sat in the aviary feeding quail meal worms when a black figure scaled down the wire... a big dirty rat so out the humane rat trap and next day there was an 8 inch rat caught. There was no way I was letting him out so I drowned him. The day after a zebra lost her tail, at first I taught it was the other zebra's but I set the trap up
