im not sure she would actually run away... the times i have her outside on teh ground to run around she some times will run back to the entrance door where she will walk inside when i open it so i think she knows inside vs outside. falling or climbing down idk if she would recognize where she was but she does have a pretty strong attraction to being in the condo here so id be surprised if she tried climbing down to the ground. that being said i could see her climbing UP as she does like to do that quite a bit
