My husband can take all the credit for this. He spent hours outdoors while big wet snowflakes fell on him finishing the castle.
The castle is so tall that Pookie can't see over the walls and I can't climb over them. There are little windows and a little door, but I don't fit through them. Hopefully Pookie won't go inside and decide to make it her permanent residence because I won't be able to go in and get her out.
