Got a drop-by visit from a neighborhood kitty this morning. This also started happening a couple days after I had to say goodbye to my other cat, Momoze, almost 10 years ago...
usually they bark and growl at him, but they were all "hey, how's it going" and the cat sat in loaf-mode until I went around the corner, and then went on its merry way.
So I interpret this as a message from Sassy, that's she's at the Rainbow Bridge, hanging out and enjoying being young again, and that she's saying "it's alright, I'm okay now"
