OMG im like that too.When I leave Felix is usually near by.To make sure he never slipped out I close the door and knock on the window till he is in my site.Hubby says im teasing him,but I just need peace of mind while im gone.Sometimes he wont come in my view and I have to go back inside to check,he is usually just around the corner,I think hes paying me back for all the times i do it to him.
