Follow-on to my previous post.
One of the most amazing animal experiences I ever had came out of that "time of the many serpents"
I saw an amazing demonstration of how animals' awareness is very different than ours, and how sensitive it can be.
A rattlesnakes (a sidewinder) was dropped off at our house - the truck that had it couldn't make the backroads to Julian's place. Julian (the snake rescue guy) was coming by to get it. We had it's cage covered so it wouldn't be disturbed and rattle.
My wife and I are comfortable with snakes. We could come and go in the room without causing the snake to rattle. Once I set something down on the table, and it made a loud noise - the snake rattled.
Our housemate, the one who was phobic of snakes, came quietly to the door of the room. I assure you, he did not make a sound. The snake rattled.
Julian came to get the snake. He breezed into the kitchen, tripped and fell, and caught himself (with a loud bang) on the table where the snake was. Then he picked up the cage.
And the snake, through all of that, did not rattle. Julian picked up the cover and looked at him, and Mr. Sidewinder was very much awake and observing, but did not rattle at all.
It was very, very interesting.
