Hi Leon
I found that, despite the hogs not being interested in dry cat food, when there was another choice, when it came to being the only one it was eaten. That was in the winter when there wasn’t much wild food around. I had a rat turn up and was trying to find something it didn’t like! (and, of course, something that didn’t freeze solid). So you might find the same.
Re. hog food. I use I love Hedgehogs, maybe not the cheapest, but I have made sure that they are very responsible about researching the right balance of ingredients, etc. Some people use Ark wildlife products.
Re. cleaning out the hog boxes. You are right, you should never clean out a box which is being occupied. Hopefully, with your straw method you will be able to find a time when they are empty, come the Spring. Just be aware that the females come out of hibernation much later than the males.
