Why is "Winter white dwarf hamster" trending?

Wikipedia Overview

The winter white dwarf hamster, also known as the Russian dwarf hamster, Djungarian hamster, Dzungarian hamster, striped dwarf hamster, Siberian hamster, or Siberian dwarf hamster, is one of three species of hamster in the genus Phodopus. Its body is ball-shaped and typically half the size of the golden hamster, so is called a dwarf hamster along with all Phodopus species. Features of the winter white hamster include a typically thick, dark grey dorsal stripe and furry feet. As winter approaches and the days shorten, the winter white dwarf hamster's dark fur is almost entirely replaced with white fur. In captivity, this does not usually happen as animals maintained as pets are generally housed indoors and exposed to artificial light that prevents the recognition of short winter daylengths. In the wild, they originate from the wheat fields of Kazakhstan, the meadows of Mongolia and Siberia, and the birch stands of Manchuria.
