First, we gave one to GG, but Tater intercepted it. Then she took the real toy I'd brought for her -- a Koozie.
Then we gave the kittens a crack at them. As you can see, they had already made quite a game out of unrolling the toilet paper all over the floor!
Then Zip decided to change it from Ping Pong to Kick Ball :--)
Here's another shot of the sisal-covered scratching post. Here you can see the platform on top.
And today when Gina got home, all 3 kittens were curled up together asleep on the top of the tree house. By the time I got my camera out, they were wide awake but did pose nicely, huh?
