I had one for Ella and she was able to figure it out. I lived on the 3rd floor and had a cheap door that was a glass slide addition to the sliding glass door. I had a balcony (she couldn't jump off) so I thought she could get some sun when I was at work. I even had a pooch potty that I filled with sod. She never used it so I stopped. I don't know if she used it but I don't have a backyard so I didn't have to worry about the other tgings. Not an option now b/c I moved to the first floor that goes out to the street.
