Ringo lounges in an upstairs windowsill. He appears to have melted!
To answer a question we had about whether Sadie and Lucy are getting along. . .Sadie has made small bits of progress. She is lounging more in my craft room (next door to the bedroom). Lucy regularly goes into the bedroom now and pretty much ignores Sadie. Sadie no longer goes into a hissy fit but still growls at her. If she's eating while Lucy comes in, she'll growl but continue to eat (though slower).
All in all, it's very slow but steady progress.
