Cats are as big a draw as the books at Twice Sold Tales on Capitol Hill. When my wife and I decided to visit the store's new location, it was partly to see how well the cats were adjusting. Our impression was that they had settled in very nicely. In fact, it seemed that every time I turned a corner and headed down a new aisle, another furry assistant approached me with a friendly smile before turning, tail in the air and back arched jauntily, and leading the way. I half expected one of them to offer a few suggestions. I presume they hid all the copies of T.S. Eliot's "Old Possum's Book of Practical Cats". They're not going to let just anyone get their hands on that title.
