Cat using the toilet to pee VIDEO

My cat uses our bathroom sink lmao I have done everything to try to stop it I ever put a piece of wood over it with a brick. He nocked it off the sink and broke the brick to pee in the sink so we have a note now above the sink that says don't use cat potty now lmao but we set it up so we can wash our hands in the shower.
I swear if the cat wasn't named after my Dad lmao
