Three-year-old William was very anxious for his first day of preschool. I'm sure most of us can relate to that in one way or another - first day of school, first day of a new job or even just meeting someone new. But his cat named Milly Moos could sense the tension and sat beside him in the morning as he tied his shoes. And it didn't stop there. The cat followed William and his mother to school and would make the same journey to go get him at the end of the day. Now that's an awesome cat!
