A hypothetical cat that is depicted as being surrounded by perfectly uncertain circumstances that make an external observer absolutely unable to deem the cat either alive or dead, especially if the possibilities of survival of the cat are expected to be analysed from the point of view of quantum mechanics. Typically, these circumstances involve the cat being inside a box while being the victim of a danger that may or may not kill it, such as radiation.
