Modelau 3D o Gathod Feline Wild Cats Pantine.

O safbwynt tacsonomeg wyddonol, mae'r gath ddomestig yn famal i deulu cathod yr ysglyfaethwr. Yn flaenorol, roedd cath ddomestig yn aml yn cael ei weld fel rhywogaeth ar wahân. O safbwynt tacsonomeg fiolegol fodern, mae'r gath ddomestig (Felis silvestris catus) yn isrywogaeth o gath y goedwig (Felis silvestris).

Fel heliwr unigol o gnofilod ac anifeiliaid bach eraill, mae cath yn anifail cymdeithasol sy'n defnyddio ystod eang o glychau i gyfathrebu, yn ogystal â pheromonau a symudiadau corff.

Ar hyn o bryd, mae tua 600 miliwn o gathod domestig yn y byd, mae bridiau 200 wedi cael eu bridio, o wallt hir (Persiaidd) i ddi-wallt (Sphynx) a gydnabyddir ac a gofrestrwyd gan wahanol sefydliadau felinolegol.

Am flynyddoedd 10,000, mae pobl wedi gwerthfawrogi'r ffelinau, gan gynnwys eu gallu i hela cnofilod a phlâu eraill.

According to a genetic study of autosomal markers and mitochondrial DNA of 979 domestic, wild and feral cats from three continents, including the dune cats (Felis margarita), all domestic maternal felines originate from at least five representatives of the subspecies steppe cat (Felis silvestris lybica), having different haplotypes of mitochondrial DNA. In the mitochondrial haplogroup IV, specific to Middle Eastern and domestic felines, 6 subclades were identified and the lifetime of a common ancestor was calculated – approx. 13 thousand years ago, which significantly exceeds the time of the alleged domestication of Middle Eastern animals. Genetic analysis of mitochondrial DNA of 209 cats from 30 graves in Europe, the Middle East, and North Africa showed that domestic cats spread throughout the world in two large waves. The first wave took place at the dawn of agriculture 12–9 thousand years ago — in the Fertile Crescent and its surroundings, domestic cats settled with farmers throughout the Middle East. A few thousand years later, the second wave, coming out of Egypt, swept almost all of Europe and North Africa.
