Miss Kit and I came down this morning to find Barry the Great hard at work. He laid some shuttering down outside my door before he knocked off on Friday, so I was not at all surprised to find that my study door opened onto a grey pool of mirror-smooth concrete (which will have paving slabs laid on top of it). I accordingly took Miss Kit out via the back door. I do my best. But any reader who shares his or her life with a cat will be wholly unsurprised to hear that, nonetheless, Barry’s beautiful concrete is now decorated with dear little paw prints. The Cats and Concrete saga has been running since the invention of concrete.
