Don't forget that Cerebella is also the Skullgirls equivalent of Brazilian, which is technically another subset of Hispanic people. (there's a lot of Hispanic countries. Brazil's a bit of an odd duck cause they were founded by the Portuguese.) Although I do think that Feline ferals are spread everywhere, they might have specific traits that identify them with a certain cultural equivalent. For example, a Russian Blue based Feral would be obviously from a Russian background, Scottish Fold for Highlands equivalent, etc.
