Examples: napping, housecleaning, etc.
Ah yes, birds love music! Mine also loved the vacuum cleaner sound. I don't know if I'm weird, or not, but when I had rugs, I liked to vacuum. Some people hate it, but I don't mind it. It's kind of satisfying, lol!
My cats couldn't give a darn, either...unless I want to clean where they are resting.
Love All Life, Thank You For Posting! :)
