yeah they are naughty cats, they dont sleep at night. I lock them in "their" room with the food and cat littler box. The will run from one room to the next and play all night long.

I haven't tried the Urine Gone yet. 

The black light doesn't work    Gonna have to return it for a new one.  It could be months before I get to play CSI: Milwaukee

JR, you'll have to let us know how it works whenever you get it working. A few years ago my cat Jack had a urinary tract infection (we found out he's magnesium intolerant. He is SO my cat.), so his litter box habits waned. There was one spot by the front door that he picked. We've used so many different cleaners there, but I'm still nervous about it. Sometimes I'll actually sniff the floor! I'm always worried that out house smells like cat pee and I just don't know it...

Man Ally, I wish I would've taken a clue from you last night! These cats were playing Herd of Buffalo Stampeding Through the Serengeti Plains all night last night! I left the door open yesterday afternoon since it was so nice out (but the screen door was closed), and they must've got just enough fresh air to get them all riled up.
