lynesco, Blackie sounds like a very dear cat indeed ! Picturing now the queue of cats in the morning waiting for Blackie to open the kitchen door and let them in to investigate.
She is a dear kitty. She looks just like our old "Blackie", (some original name!!) She was the smartest cat ever. She knew how to open all the doors, and the other cats would line up and wait for her!! I really miss her, and she was like my "sister" too.
