Tin Foil Training.

Yesterday evening I covered the hall carpet in tin foil. 

It looks as though crazy people live in our house, and they are trying to stop the aliens reading the floor's thoughts.

Actually I'm still trying to find a way of discouraging Edith from peeing by the front door. It's a technique I read about on an internet forum, so either this is actually going to solve the problem, or it's a low tech and particularly cruel variation of rickrolling for cat owners.

So far the results have been, um,.. mixed?..  But I am cautiously optimistic, please keep all fingers and paws crossed for us.
