Cookie loves entertaining herself by Surprising the Kitty Carers as they walk past her door into the building. She would have to be in hysterics. She gives us a small fright as she stealthily launches up from the ground and does a star jump onto the mesh and meows at us. We reacon her meows are cat talk for "Gotcha... Gotcha again!" She gets a bit too much enjoyment from this we think.
You will just have to take the Kitty Carers word as when there is no element of Surprise (like when you are trying to photograph this), she refuses to play.
