The scientific naming system used for all organisms is called binomial nomenclature, which was developed by Carl Linnaeus. According to this system, each organism is assigned a unique two-part name, consisting of the genus name (with the first letter capitalized) followed by the species name (all in lowercase).
In this case, the domestic cat's genus name is "Felis" and its species name is "catus." Therefore, the correct format for the scientific name of the domestic cat is "Felis catus."
