She is back behind the piano and still miaowing quietly at practice time.
However do you remember that I said a few weeks ago when she went up the chimney that it was better than the piano because it is easier to reach her? This was wrong. I had to get her out of the chimney to take her to the vet for her jabs and it ended up with me looking like a chimney sweep and the entire room covered in brick dust and lumps of rock. The only saving grace was that she is an exceptionally gentle cat - any other cat I’ve met would have got spicy at some point during the stressful extraction process.
So on balance she is welcome to her spot behind the piano now.
