Her name is Marigold and her purpose in life is to torment the dog.
She is also an escape artist. She has made a (cat sized) hole in the top of the screen door (twice) and she escaped into the ceiling at the vet’s office. It took them an hour to get her back down. When she wants to come inside she climbs up to the 2nd floor bathroom window. She has to scale several roofs to get there and she can’t come in that way, but she yells at whoever is in there to let them know that they need to come down to open the door.
