Cats are territorial, but as I’ve noted in the past, ownership can change.
Case in point: the Condo at the Top of the Stairs* was previously Lefty’s spot. Not that he went inside much, but he frequently sat on top of it. Before Lefty took possession, Watanuki was a frequent resident.
* We’re still not sure if it’s supposed to be a TV or a microwave. Certainly the controls suggest the former, but the overall impression seems other. Perhaps it was designed by someone–probably on commission–who’d never actually seen a TV old enough to have a UHF dial. I can see him deciding that a Google Image search would be too much work. “Hmm, that microwave has a couple of dials and is square and boxy. Good enough.”
With the library–currently aka “Emeraldas’ Room–being open most of the day and night, Lefty is spending most of his time in there, leaving the CatTofS vacant. As we saw a couple of weeks ago, Yuki gave it a test, but ultimately he seems to have decided it’s not for him.
Never loathe to stake out turf in a high traffic zone, Sachiko moved in.
Not that gloats about her new habitat, of course.
She just has a smug resting face.
