They say it might be the nuts around Knutsford that attracted this vicious beast...

This brings to mind the 'Super Squirrel' that I wrote about back in June. That one came into our house and was quite a pest in the neighbourhood for a while. I think someone trapped it and took it away in the end.

Must something in the water getting to them!

...or the steady supply of NUTS on that side of the pond! Harharhar! Honest, though, telly, I did think of your squirrel situation when I posted it!
