Andy and Bugsy, best buds!
This is more of a statement than a question. We've had many cats in our household, and from my experience typical cats stay in your lap until they are ready to leave and then they abruptly jump off. That's just an endearing cat trait because they are so independent. However, our dear departed Milo stayed there and just snored until we removed him. Our current Bugsy does that as well. He will stay there for hours and I just pick him up softly and move him to a different area of the couch so I can get up. Weird how cats are so different.
