Pros: Kitties have a blast with it, gives them something else to scratch
My kitties particularly enjoy this toy at night, mainly because the dogs are in bed then. Penelopy went NUTS over the foil ball inside. She always manages to pull it outside of the hole; I put it back in every day and every morning, it's back out. The boys like to climb on top of it and then jump on each other, as well as Penelopy. Sara, one of my 13 year olds, likes to take a few moments to scratch in it every now and then.
I was literally looking for inexpensive stocking stuffers when I saw this, and saw that it was so cheap! Obviously doesn't fit in a stocking, but so glad I got it. And I did have the catnip, but I like to use my own anyway. I did that yesterday and the boys were all over it!
