My cat is a Sinatra fan. Ever since we adopted her almost 8 years ago, she comes over to listen when I play his music. We have a giant stereo system in our living room (ancient, from the days when you needed a 24" speaker to get the same quality sound that comes out of a 5" one today) and she literally camps out in front of the speakers on the floor whenever I put Sinatra on.
Today I was a little afraid she wanted to take a spin on the record, but she just sat there patiently, listening to her favorite singer croon some of her favorite tunes :)
