You have all been so kind, and indeed I am coming round to the idea of the rogue squirrel, even though it hasn't happened before like this. Thanks for the kind words, they do help! I've emptied the worst damaged pots, and will refill with something lovely - with fine wire netting over them, interspersed with cuttings from the pyracantha and see what that does to the rogues ego.
No deer in the area, and no peacocks - that would at least be unusual enough to be interesting.
Knowing my co-ordination if I used an air rifle, I'd probably hit the neighbours! Not for me, but thank you.
Any more ideas welcome.
