In comparison to dogs, cats have not undergone major changes during the domestication process, as the form and behavior of the domestic cat is not radically different from those of wildcats and domestic cats are perfectly capable of surviving in the wild.
A 2016 study found that leopard cats were undergoing domestication independently in China around 5500 BC, though this line of partially domesticated cats leaves no trace in the domesticated populations of today. Cats have either a mutualistic or commensal relationship with humans.
