Hi Margaret
Yes, I would say that water is even more important to leave out than food. The hogs have some chance of finding ‘wild’ food, but not always water.
I think hibernation is more complicated than just availability of food and the temperature – although I’m not sure if anyone has completely worked out quite what it all is about – if that makes sense! You may find they or some others may still make an appearance, so I would keep leaving some food out in case. As I keep saying, often newly independent hoglets turn up at this time of year.
