Nothing will shift the stink of cat's P-one hundred-and-fifty-five, except burning the affected item, in my experience. Tom-P155 is the worst formula, they mark out territory with horizontal bursts. It ain't ammonia, it's some sort of hormone/pheremone mix.
I quite like tom-cats, and we used to get 'em spayed before they reached pubity to stop the squirting behavior. It stops them going off on two-year sex-jaunts too, then coming back half-dead and covered in battle scars, fleas and mange.
As to mouses, I was in the shop one day, being real quiet reading some stuff, and a mouse emerged right by me, between two oak boards. Aftewards, I measured the gap it came through. Just a tad under 3/8" (0.375"). How do they do it- dislocate their joints, or what?
