Having said that Maisie is very well behaved and comes to my whistle at night she isn't perfect. Last night she went out at 7.30pm and despite my constant calling never returned. I was wandering up the drive at 12.15am calling her but no sign so I went to bed. After a restless night (I don't need this!) at 6am she was sitting on the front door mat looking very sheepish. She didn't meow or purr as she normally does when she comes in but ate well and then slept for most of the morning. Tonight she's decided to stay in.
