Guilt isn't in cat vocabulary. They never suffer remorse for eating too much, sleeping too long or hogging the warmest cushion in the house. They welcome every pleasurable moment as it unravels and savour it to the full until a butterfly or falling leaf diverts their attention. They don't waste energy counting the number of calories they've consumed or the hours they've frittered away sunbathing.Cats don't beat themselves up about not working hard enough. They don't get up and go, they sit down and stay. For them, lethargy is an art form. From their vantage points on top of fences and window ledges, they see the treadmills of human obligations for what they are - a meaningless waste of nap time.
