I bought my kitten this today, and she is going batshit crazy playing with it. I had it on the floor and she was like half interested; I put it on a chair so that a climby aspect would be involved, and she is all over it attacking the balls on it and sitting inside and sniffing it.
So now I want to get her this so she can climb more and have more to play with.
Hopefully this will help her learn to stay off the table and the bookshelves, and on her house.
Except I have to talk myself into letting myself spend the money.
