I don't know...Hanna, despite the sorry state she was in when I found her (skinny, sick, hungry, burned whiskers) isn't afraid of much. She is not afraid of most people, the dogs, the vacuum cleaner, not much scares her. But one day I was holding her and my boyfriend walked through the doorway with a load of clean laundry - and Hanna went ballistic. She scrambled away and ran and hid. She has never reacted that way again, but it was weird. Maybe Luna thought it was something else?
