"One of the many ways in which cats are superior to humans is their mastery of time. By making no attempt to dissect years into months, days into hours and minutes into seconds, cats avoid much misery. Free from the slavery of measuring every moment, worrying whether they are late or early, young or old, or if Christmas is six weeks away, felines appreciate the present in all its multidimensional glory. They never worry about endings or beginnings. From their paradoxical viewpoint an ending is often a beginning. The joy of basking on a window ledge can seem eternal, though if measured in human time it's diminished to a paltry eighteen minutes."
