We all got together for Thanksgiving (me, ex, kids) and when we were grocery shopping for Thanksgiving, I said, "Kids need this for the cat..." and grabbed a cheap package of 2 laser pointers. Kids had a ball with the cat (Ok, I had a ball with the cat, LOL.)
The next day they put their tree up and I got a text, "Can't keep the cat out of the tree. He keeps climbing up and going after the red bulbs!" LOL.
