Hi Ollyowl
Welcome to the Forum.
If I was looking at the right one, I have a hog house exactly like it and despite reducing the size of the entrance, at least one of the cats round here can still get in. A friend made another one for me – same dimensions but smaller entrance – with an extra corridor inside (so 2 bends past the entrance) and a cat could still get in eat the food and get back out again. So you are lucky! The only thing that has stopped them is putting bricks in to reduce the height of the tunnel. The only problem is some hogs don’t like going into boxes to eat!
But I do think that the location of the tunnel on those hog houses are the best. Some have the tunnel going straight on from the entrance, which would be really easy for cats to get in.
Good to hear about the youngsters. Fingers crossed for them. Hogs, especially hoglets, sometimes decide not to hibernate even if they are big enough to. But if that happens just keep offering food and water.
Good luck and happy hog watching!
