Earlier quoted context omitted.
Cats don't need help breeding. GP even said "feral cat". I don't know of any "cat breeders". They are just a resilient species. I suppose we could make some sort of "equity" system for species based on an arbitrary metric, but that's closer to playing God.
Domestic cats as a species had been introduced to America by humans, and still are explicitly kept and feed by humans. I'd call that breeding. This also sets an easy and natural metric of how many cats should be there: 0.
Same applies to humans of non-native descent, I presume?
