You can do the spraying once a week, that should do the trick Cookie and it will keep them fresh and clear of pests. As far as the cat goes what I have tried with some success was to mix a small bowl of the liquids and sit on the floor or sofa and use a cotton ball to dab it onto the cat while petting and rubbing her. It doesn't have to cover every inch BUT get around the head and neck first and also the tail and under the tail. Most cats will tolerate this just fine....
