Do you have any tile floors or linoleium(SP?) floors?
when Muffin came into heat,, we tyed her up in the kitchen which has a linoleum floor. and most of the walls and cabnits were coverd with wallpaper. so it was fairly easy to wipe any messies.

then we'd mop with hot soapy water on any of the walls and the floor in there and sprinkle that stuff that makes your carpets smell good thast supposed to get rid of pet oders in any of the carpted ares after she was out of heat.
