Last night, Merlo went missing. I realised she was gone sometime around 8-8:30, and I hadn't seen her since around 7:00. Raoul and I searched the entire house over several times, and called and called outside. She didn't come, not even at the sound of food in her bowl (and she hadn't even finished her supper, so she had to have been hungry). Merlo never really wanders from the house much. The longest she's been away before has been maybe half an hour or so, and she usually comes soon after she's called.
