My cat does the craziest things when she thinks we are asleep. She pees in my bathtub and covers it with towels, gets behind my couch and lays down on my shoes!
Also, everytime we put the bags on the floor to pack for the holidays, she very, very slowly sneaks away and hides. She hates travelling!
She only drinks water from the sink. She uses the water bowl to check her reflection, it's too cute! When she was a kitten, she also drank from the toilet! lol
And she once turned the electric stove on by herself, at that time we didn't even know how to turn it on ourselves!
