Aaah...Gizzy looks very content on his beautiful plushy bed. See he's a paper shredder...."hey mom, gotta do something when you're not home!" Have you tried giving him a small size Kong toy, with a few treats in it before you and bf leave? That will keep him busy for while trying to get them out.
The important thing is....has this arrangement stopped his spraying when you are at home and he's out of his crate?
