My better half observed that our last cat (Samantha) "owned" the house immediately after she arrived. Our latest pet, Abby, has only just now moved in. She had previously claimed only the area beneath the beds, although she would emerge for food and playtime.
Now, Abby has claimed places throughout the house. One of her favorites is the top of the radiator cover (this house uses hot water radiators for heat) in the hall bath, where the heat from the radiator (and the sunbeams from the window) lull her to sleep.

Downstairs, one of her favorite spots is the top of the wingback chair, where she can view three windows as well as the living and dining rooms:

And in our bedroom, she likes to perch on the dresser near the bathroom sink, so she can supervise our morning preparations (although this picture sees her somewhat distracted):

If we sleep too long, Abby starts dumping everything stored on the top of the night stands onto the floor.
Abby has definitely moved in. :-)
