If you have company coming over and there is pet hair all over the couches, here is a quick fix. If there is no time take out the vacuum, put on rubber gloves,wet them and run your hands over the couches and the rubber will quickly lift shedded hair. A wet cloth will do the same thing.
If your cat loves to drink water from a running tap, consider getting a drinking fountain for her. Cats in the wild drink running water and a pet drinking fountain recreates this in the home.
