Query: This book is a natural High!

Not only is this the best addition to the Cat Who series, it reminds me so much of my own treasured one, Mr. Cheddar. No need to get a permit for renovations, this book towers above other cat-related mysteries! I am tempted to get another cat just to name it Mr. Yumyum and see if I too can teach it scrabble.
