If you have at the very least a weekend, and ideally a week or so for her to get used to your family, then it may be a good idea, but be on the lookout for bad habits that may not work with your household, (i.e. spraying, chasing cats, tearing carpet, etc.) And make sure that you have carefully supervised the dog with the cats and are sure that they all get along before you leave them unsupervised together. And also expect accidents at first, they may not happen, but be prepared for them anyway. If you cannot spend the time in the beginning, then it's not fair to her.
