If your cat leaves mini-kitty wigs wherever she goes, consider whether this will bother your guests. It is courteous to vacuum the furniture, floors, and other locations full of cat hair just before your guest arrives. It is also ideal to brush your cat to remove as much loose hair as possible and minimize shedding during the visit.
Do your best to keep the shedding cat away from the kitchen to avoid unwanted fluff in the food. It is also best to keep the her off your guests laps, or at least provide a lint brush.
If you feel that cat hair will be offensive to your guest, you may want to confine your cat while you have company.
