Observations of an object alter the properties of the object. That is what the supporters of quantum mechanics say. And I was three months watching the cat hanging under the couch and nothing changed. I was tired of it and I remembered Newton’s second law. And again gave the mass of the cat some acceleration with a tap from the leg. It’s not me, but the cat watching me. He is in the right place. Plus a minus on the coordinate in the toilet in your bowl to the Planck constant for two.

Not “observation,” but “measurement of state.” Try to use on a sucking cat at least a stangensirkul, the result will surprise you.
