That is so cute - I didn't realise they did that. I can't believe how quickly they've both settled in, mine didn't relax until her first full day at home, and even then I used Feliway. She's taken over now, of course!
I'd love to have two of them, I just can't convince my better half - he's worried that he'll feel guilty and disloyal to Freyja if we had to love two now. V jealous!
