They are adorable - wonderful little kitties. What is the blue slinky looking tube attached to the water tap - I have not seen anything like that before?
It's a garden hose. The self-coiled hoses have been selling here for some time and are popular.
The kittens love it. When they were smaller, they would use it like a little fence to "protect" them from big, bad me. Now they can jump over it with ease. China (the one with the black chin) loves to crawl in the center, then bat at her sisters from inside where they can't get her. :)
