Unfortunately for Soprano’s owner, she loves singing and listening to music. If he was going to be forced to listen to high pitched songs for most of the day, he was at least going to make it more tolerable for him by encouraging her to sing along to classical music instead of the annoying vapid songs that are normally made for Fluffies.
This had an unexpected side effect, as now Soprano has a taste for music that would normally scare the shit out of any other Fluffy.
