@Terri38 that story gave me a chuckle. Though your poor guest must have got the fright of her life!
My upstairs neighbour has 2 cats that love sitting on the balcony railing & surveying the sights. Unfortunately they are very clumsy & fall off the balcony onto my terrace with regularity (no harm comes to them, apart from hurt kitty pride). The last time I was woken at 3.45am by a sad meowing cat outside & then the upstairs neighbour ringing my bell to collect him. Thankfully I didn't have a guest that night, they would not have appreciated being woken up at that time!
