Well, he's definitely back, despite his tree-home being chopped down by the neighbour, and he's even bringing a friend every day. I think it's the same friend as the one last time.
Both squirrels have been coming every day, several times, too, to eat the cat's leftovers. And this is despite the massive drilling and hacking in the neighbour's house (which is contributing to my migraine!!).
The other friend is really shy, so I didn't manage to take his photo.
