I know it looks like theres no hardware cloth there but there is. We have really wet ground so we but our bottom wooden supports up off the ground on a block. Then dug a 2ft deep trench around it and put 4 ft hardware cloth, 2ft above and 2ft below the ground all the way around. I think it's a mole. There tunnels I keep stepping on inside the enclosure. The only thing I can think of is he crawled in through the door. Unless the can go two ft below ground. The yellow spot is where the hole is.
