My cat runneth over

It was something of a surprise when I saw Rocky the cat through one of the dining room windows sat on top of one of our water butts. That's a first and quite a leap for Rocky to get up to it. Storm Bert has been felt here today with strong winds and intermittently heavy rain although nowhere near as badly as elsewhere in the country. We have three water butts and they have been filled to brimming for some time even before this weekend's rain. Not that the elements put Rocky off heading out into the garden a few times today albeit never longer than 40 minutes or so. I'm intrigued by the naming of storm as Bert, rather than Albert. What next, storm Fred, storm Dave.....?
