Last Sign of Autumn?

Throughout the summer we have been visited, in the evening, by a hedgehog and as the days got shorter the adult was accompanied by 2 hoglets. They have shown a great liking for the meal worms that we put out and so we have been putting out extra for them. About 2 weeks ago first the adult and then one of the juveniles stopped coming, hopefully well fed and hibernating. We have now not seen the other one for about 4 days so we are assuming that this one has grown fat enough. Here is hoping for a quiet winter for them to get lots of sleep and then carry on clearing the garden of slugs etc. in the spring.
