If you do try the cage, I think he may complain but all of mine , first just loved being where things were active and second, if they complained they stopped once they learned it was not going to change the way things had to work. They did settle down and all of them still like to go into the cages. I have them in the cat room and they like to take naps in them. Lol Private retreats! Not sure about having the music 24/7 but you can always try it to see. Every cat is different so we can’t predict exactly what Finn might like. I’m all for trying things to see what they like.
