Where do domestic cats come from?
An interesting question, asked and answered in Veterinary Practice Sept 2010. Current evidence shows that domestic cats derive fom Eurasian cats, possibly with migrations to and from America via the Bering land bridge. African cats share an ancestor with the domestic cat, but are not themselves ancestors.
