One thing Dave likes to do is lodge himself between two objects. Usually, he chooses two objects that are each comfortable enough to nap on. This is a strategy he finds particularly useful in the winter months, and it is called "The Crevasse" strategy. In the example seen below, Dave has lodged himself between a pillow and a person. Dave doesn't have a great grasp on the English language, but if he did, one of his favorite words would be "crevasse". Dave would love to explore a crevasse like this one. While he typically prefers warm napping locations, he is also an explorer. Any opportunity for exploration excites Dave, and he would gladly explore a crevasse in a glacier, despite the lack of warm napping locations. Other cats might balk at the idea of a glacier as a napping location, but Dave's dexterous napping abilities simply afford him opportunities not available to other cats.
