What animal takes part in Schrödinger's most famous thought experiment?

The animal that takes part in Schrödinger's most famous thought experiment is a cat. In this experiment, an imaginary scenario is created where a live cat is placed in a sealed box along with a vial of poison that could be released by a random event, such as the decay of a radioactive atom. According to quantum mechanics, until the box is opened and observed, the cat exists in a superposition of both alive and dead states, representing the uncertainty of quantum states. This experiment was proposed by Schrödinger as a way to highlight the absurdity and paradoxical nature of applying quantum principles to macroscopic objects.
