Looks like it's official, since this showed up on Amazon yesterday. It's the cover for Home for the Homicide, DIY-7, scheduled for release December 3rd.
No, Mischa the kitten (on the floor with the Christmas lights) still doesn't look like a Russian Blue. And Inky (on the table) is more gray than black, while Jemmy (the tiger striped Maine Coon) isn't on the cover at all this time. Nor do I have a creepy shadow, it seems.
However, all that aside, it's a beautiful cover as usual. The book is available for preorder at the moment, for $7.19 (a little off the cover price of $7.99) - on Amazon.
