Hi jackietb
Sorry to hear the little one didn’t turn up. Fingers crossed it might visit tonight.
Bricks in a tunnel work really well as cat deterrants – possibly even bettter than tunnels. The idea is that if the cats have to flatten to get over the bricks (i.e. the height is shallow there), it isn’t so easy for them to turn. So ideally if you have a turning place, the best place to put the bricks is either side of that. So just inside the entrance is not necessarily the best place – depending on how yours is constructed. But you could also put bricks/earth filled flower pots either side of the entrance so that (if the passage turns immediately left or right) the cats can’t get at an angle to get in – as an extra deterrant.
I’m not sure how the cats seem to know there is food for the hogs around again! I hardly had any visits during the winter and now as soon as a hog returned, they’re back. Luckily the hog visiting at the moment is one who doesn’t mind going into boxes. So far the cat who is normally a bit of a houdini hasn’t managed to get in.
Good luck. Hope the bricks work and there is some food left for the hogs!
