I am cat-sitting for friends who are vacationing in warmer climes. I am mildly envious of their escape from winter. At the same time, I have no desire to break my hibernation habits. Fortunately, hibernation does include leaving the house for the purchase of groceries and other items. So it's easy enough to include the feeding, watering, and belly-rubbing activities associated with the care of cats in these outings. As far as they are concerned, all of this is necessary. Especially the belly rubbing. Cats are so self-centered.
