Where in space were the chemical elements that make up your beloved kitty formed? A golden statuette of your favorite cat? Diamond pendants on the statuette of your beloved cat?

A beloved kitty, like any living creature, consists mainly of carbon, hydrogen and oxygen, nitrogen, sodium, sulfur, chlorine and other elements of the first periods of the periodic table are present in smaller amounts, there are very few elements heavier than iron in it. The diamond from which the pendants are made is also carbon. Hydrogen is the first chemical element that existed in the Universe even before the formation of stars and galaxies. All elements heavier than hydrogen and helium, up to iron, were formed in the Universe in the cores of stars during their evolution. Atomic nuclei were produced by the fusion of lighter nuclei, and this process provided the stars with their energy release. The heavier the element, the more massive the star in which it was formed must have been.
However, elements heavier than iron, in particular gold, of which the statuette is composed, could not be formed in this way, since, on the contrary, energy must be expended for this. Heavy elements appear only during supernova explosions, and every atom of gold in the statuette once witnessed this colossal cosmic catastrophe.
