My Son was just telling me that toy did have a cover over it and the arm went under it, making it look like something was moving underneath. The kitten (no name yet) destroyed the cover pretty quickly and now the arm isn't even moving like is should.
He also says the kitten runs sideways at the other two cats playfully, and that they are getting more used to each other.
Every day when my Son comes home for lunch he takes a little nap and the kitten climbs up on his chest and goes to sleep too. I knew he was going to be a lap cat.
