About a year and a half ago, when the construction work started next door, I set this place up for Webby so he could keep an eye on the activity (with the blinds opened a bit) & snooze when things were boring.
It turned into, and has remained, Webby's routine morning spot.
Until a week or three ago, Archie left it alone. Butt hen I started occasionally finding him there instead of Webby.
I didn't know if Archie was displacing Webby or simply taking advantage of a vacancy.
Then the other day I found this scene - apparently some kind of truce (disgruntled?).
No recurrence since, that I know of, but I'm keeping my eye out.
