Thanks for that Doug.

Very interesting.

Amazing mimicry as well - does convey the actions of a snake to the tee! Given that a lot of animals, birds, snakes etc may largely use shape as a distinguishing factor, this is particularly effective.

In the case of our cats and shapes, they will run away from strangers. I wear a number of hats, but if I put on a new one or one I haven't worn for some time, they run away!

In the bush, I have also seen lions, leopards, cheetah, hunting animals. If the animals they are hunting moves so that a vehicle or building becomes the "background", the cats lose sight of them. When they move away from the object they become visible again.
