Domesticated animals are different species than native flora and fauna. The domestic cat is taxonomically and genetically not the same as a any wild cat. The same goes for dogs, cattle, etc.
By definition, domestic animals and plants have no native home except with humans. This is why we call domestic cats who escape and live in the wild "feral," not "wild," because a feral animal is specifically a domestic animal not living with humans, not a non-domestic native animal. It does not matter whether they 'domesticated themselves' or not, they are a domestic species and therefore not equatable with a wild one.
As a result, your point simply makes no sense. Domestic cats have no 'native lands' because they are not and cannot be 'native' anywhere except in human settlements.
