Hi Palladium
I do recall someone trying out an automatic feeder, but I think it didn’t work as well as hoped. But there are probably all sorts of different types available
However, what we feed the hogs is only supplementary, so that they should be able to manage without it for short periods of time. Having said that, I know most people don’t like to think of the hogs turning up to find nothing there. Your best bet is to ask someone nearby to top up their food. The most important thing, though, is that you leave a good supply of water. Large plant saucers are ideal and the water lasts for quite a while. I always have these around the garden.
In the long run, more important than feeding, is to make your garden as good a habitat for the hogs as you can, and link gardens, so that they have a good supply of wild food. Tips for improving your garden

and importantly, link your garden with as many others as possible
