I know my best friends grandpa had a cat that would sit on the vaccume cleaner when he was vaccuming...
that cat would also play hide and seek with him!
(seriously grandpa would hide and the cat would look for him)

My sisters ex had a cat that likes water.
I even took him (the cat!) in the shower with me once, because he wouldn't leave the shower, so I just closed the door and he got wet.
After that he became half the size he looked like at first hahaha!
