Ok.. my cat Fern loves to play with light- either from a flash light, or light being reflected from a mirror. She loves Lauren's mirrored toys, and comes around as soon as she notices Lauren touching them. Today I was making a circle of light move all over the bedroom floor, and Fern was chasing it (she looks like a maniac when she does it). Suddenly, Lauren laughed! It is the first time that something other than a silly sound or face has made her laugh. It was SOO cute!! I've been waiting for her to do it, and it was just a matter of time. I smiled as she continued to laugh- that is until Fern got tired of running. LOL
