All cats are weird...that`s part of their appeal.
I had a retrieving cat once...he used to love it at birthdays and Christmas when a champagne bottle was opened. To entertain the kids once, I opened the kitchen door and fired the cork to the bottom of the garden this event was immediately followed by the cat hurtling down the path and fetching the cork back....from then on, whenever he saw a champagne/cava bottle being brought out, he would ready himself for what had become a ritual.
Same cat loved jazz, and would come in from wherever he was to listen to the stereo; didn`t think much of Stan Getz, but adored Miles Davis. He was quite partial to Ella Fitzgerald too.
