Step 1 : Introduction to the question "Only cats that live in groups?"
..The Germanic word is generally thought to be from Late Latin cattus (“domestic cat”) (c. 350, Palladius), from Latin catta (c. 75 A.D., Martial), from an Afro-Asiatic language. This would roughly match how domestic cats themselves spread, as genetic studies suggest they began to spread out of the Near East / Fertile Crescent during the Neolithic (being in Cyprus by 9500 years ago, and Greece and Italy by 2500 years ago), especially after they became popular in Egypt. However, every proposed source word has presented problems. Adolphe Pictet and many subsequent sources refer to "Barabra" (Nubian) [script needed] (kaddîska) and "Nouba" (Nobiin) kadīs as possible sources or cognates, but M. Lionel Bender says the Nubian word is a loan from Arabic قِطَّة (qiṭṭa). Jean-Paul Savignac suggests the Latin word is from an Egyptian precursor of Coptic (šau, “tomcat”) suffixed with feminine -t,but John Huehnergard says "the source [was clearly not Egyptian itself, where no analogous form is attested."[8].
