Yeah, mousethief, I had several back in the early 1970s when I still lived with my parents. My first and favorite was Simon. He's the one I took to the movies.
I used to let him run free around the house some of the time, and he would come when I called him. At night, he used to like to go check on everybody while they were sleeping and then he'd come and beg food from me to take to his nest.
