Sounds like spellcheck has been playing tricks again! Although jolleys is a better name for hoglets than it could have been!
But, P.Holmes, the answer to your question is that, yes, cats will eat hog food. But so will birds. But I agree the mice and slugs probably wouldn’t get through much. Funny how the cats are never around when the mice are!
But the hog there could very easily be hibernating now. If it had already been spending days in your box, it wouldn’t be surprising if it made it’s hibernaculum elsewhere – good practice to avoid a built up of external parasites, such as fleas and ticks. But it’s possible there are other hogs visiting your garden, who don’t use the box.
I can sympathise re. the cats! You might want to try to make a cat-proof feeding station – there are loads of ideas on the forum where people have tried – with varying levels of success – to keep the cats away from the food. Jackietb’s idea of a cold frame sounds brilliant – a nice lot of space and presumably ‘windows’ that you can see the hogs through. Getting the entrance right is the difficult bit and sometimes needs a bit of trial and error – sometimes depending on how persistent the cats are in your area.
You might condsider getting a night cam, so that you can see who is eating the food.
Good luck.
