The Cat's Schrödinger and the Determinate in Schrödinger's Cat

Working from the German original of Schrödinger’s well known thought experiment (here given in translation), this paper sets out several ideas that are known and determinate in Schrödinger’s cat. The first is the cat’s Schrödinger — that is, the cat putting Schrödinger into the steel box. The most important one is that atoms of the same isotope differ. And so on.
