In my previous post, I mentioned we were away a few days; the cats were left in the care of our eldest son whom both cats adore. When we returned, Maddie was sitting in the big front window watching for us. After time for greeting both he and Polly, we checked the phone messages and found one from our cat-loving neighbour, quite late the previous night, saying that Maddie was crying at her back door and she wondered if we knew he was out. She had tried several times to get him to come inside (because it was -20) but he wouldn't. This sounded odd for a couple of reasons (one of which is that Maddie never cries, he is a silent cat.). I contacted my son to ask if Maddie had escaped one night but he assured me neither cat had been outside the whole time we were away. We knew immediately what was going on!
Their tuxedos must have been made by the same tailor as the cut and colouring is almost an exact copy. They have the same bouncy gait. Impostor Maddie even has the same sleek, shiny, thick fur as our Maddie.
