Lucky Shiloh! I voted for both the Spiral Penthouse and the Amusement Park. The penthouse seems to have the easiest access to all levels; the amusement park looks like it could present a challenge for her to reach the plateau . . . I have one with a tube and my husband had to modify the position of it so Debra could use it more easily to go up to the top level. But the style of yours looks like that sisal post in back goes all the way up, so Shiloh could simply climb to the top . . . ? Whichever one you choose, I'm sure she will be delighted!
