You will have an activity rope for hanging toys and such. These are replaceable and you can order these along with other stuff that goes with the activity center. These toys are very nice looking and different from other toys that you see in supermarkets or pet stores. Very pretty colors and durable too. I think that you will be pleased with these.
Some places are less expensive than others, of course.
What is available is a Dream Sleeper platform. This is a nifty thing too. It is framed in wood and will match the posts. It is soft and desirable to a cat. It has a sleeping material that is soft to touch.
