By no means an expert, but hope this helps;
Leaving some areas a bit wilder is always good, if you can don’t cut the grass too short everywhere leave some a bit longer. Don’t go ott on outside lights if you do have them outside make sure they are dim ones – mine prefer wandering in the dark. Log piles are good which encourage Beatles and bugs which is the natural diet of the hogs, they eat less snails and slugs than you think which also have a risk of parasites so the more Beatles you have the better. A wildlife pond is good not just for the hogs but other wildlife too (size isn’t crucial easy accessibility is), it doesn’t have to be a lake a bin lid size is fine as long as it’s easy to access and will be used as a bird bath too.
Depending on where you are cats can be an issue getting the food – when it comes to feeding, Penny on the forum has an excellent home made feeding station design on the forum, which touch wood has flumaxed the locals cats so far and is more attractive in the garden. Always make sure there is fresh water available, they drink as well as eat.
As for the hog home – put it in a sheltered spot not facing the prevailing wind / rain and not in direct sunlight. I have mine tucked under a Christmas tree which has wide branches low down this helps protect it from predators etc… so under a bush would be good if you have one.
Don’t forget a comfy chair and a big mug! It’s very addictive watching those hogs!
Happy hog watching. 😀
