I've been wondering if Shona made it back to her favorite spot, and am so happy to see that she did. You will miss her, I know, and so will Bogie for a while. She lived a very full cat's life, and chose to go in her own manner.
Hugs to you, and I hope your cold is better so you can enjoy being in your great spot. Would love to see some pictures of where you are, when you are ready.
Licks from Molly, too
