Hey sweety, im fine. How are you?
Well hmm find out exactly where the smell is coming from (the source) and clean it well with either tile cleaner, floor board cleaner or a carpet cleaner. Open up every window around the area where the smell is fuming from. Put a fan near the source of the smell while you scrub it well. Then spray some house air-rid smell thing around the house while the windows are closed. Then open the windows again.
That SHOULD work, if it doesn't then geez the cat must be drinking something strong like tequilla lol
peace.
