There's a folk belief (or maybe a legend of such belief) that when moving into a new house, one should let in the cat first, observe where they choose the resting place, and promptly install the bed there.
It's a very sensible belief! Cats are quite sensitive to drafts, so (especially in days when houses were draftier and lacked central heating) sleeping in the location the cat picks is likely to be much healthier than picking a location at random.
