This is Fleas4U, the neighbourhood cat who has made friends with us all in the hope that we will feed him, cuddle him and call him nicer names than that.
He shows up at the kitchen window on chilly days and says 'Meep' in a sad voice, but he blotted his copybook a few weeks ago by copiously spraying on the window-cleaner's waxed Barbour jacket.
Up until that point, we'd been wondering if he was a male or a female cat, but he found the most powerful way of telling us. Pity he aimed for the internal pocket, too.
The window cleaner was very reasonable about it, but hasn't been back.
