My 5 older adult cats grew up with my playing guitar and singing, and they seem to enjoy it. It's mostly 60s and 70s classic rock.
The three young ones, barely not kittens any more, seem to see it as playground equipment. I attached a capo to one's tail, and that was rather funny.
She looked like a small tornado trying to shake it off.
Cats tread lightly but leave their pawprints on your heart.
