The water bowl gets picked up and the toilet lid goes down at 8pm every night. He NEVER pees in his crate when he's in it, so I know he's able to hold it. It's just that when he doesn't have to hold it... he won't!

Buddy's thoughts: "Oh I got to pee..... but Mom's sleeping. Oh lookie.... mom brought a tree inside for me to potty on!! What a great mommy!!"
