Your cat may want to go out for more than getting dirty. Usually, all a cat wants is to sleep and play (and of course eat). To keep your cat safe, be sure you put screens in the windows so the cat can't fall from the sills. To keep your cat inside make sure your cat has plenty to occupy her while you are busy. A TV or tablet with moving fish is a good one to keep her busy, but also cat trees and plenty of toys are necessary. Be sure to play with your cat as well. This helps to build your bond with her as well as keep her happy inside.
