Hi Kredski
If you look at my reply to JFDrake above, I explained the arrangement I have which seems to have worked to keep cats away. I have the perspex type stuff a couple of inches away from the feeding box entrance. So you can put food under the perspex (for the hogs who prefer to eat out of doors) and it also stops the cats from getting into the hog box, so that food can be put in there. I thought I had found a food that cats didn’t like, but you will find there is always one cat who will eat it!
Another thing you can try is if the ‘corridor’ of the feed box goes immediately left or right you can put an obstacle the opposite side (i.e. largish plant pot filled with soil – or something else heavy enough that a cat can’t move). I found that if cats were going to get into boxes with that sort of ‘corridor’ they needed to enter at an angle and with the obstacle there it makes it very difficult. But since I have had the set-up mentioned above no cats have got into the box.
Good Luck
