Guest loses her cat at the rental property--help what else can I do for her?

[Anasazi-Cliffs-Lodging0]

Howdy there,

 I need some advice on reassuring me that I am doing things right with this reservation. I had a guest loose her cat while at the rental property--we scoured the whole property, posted pics on social media and had a couple of good neighbors helped. I refund her the cleaning fee since there was someone else there when she arrived (another guest entered the rental by mistake). What else should be done to help this guest? Your advice is greatly appreciated. Thanks!
