It’s an interesting idea. If they always were intelligent, then yes, they’d probably have their own nation, or maybe they’d even be integrated with us in a society that accommodates for both of our form factors, but I’m sure there’d be terrible racism concerns because if we’re this bad to people who look relatively similar to each other, then we’d be just terrible to a very different intelligent race.

But, if they suddenly became sentient through some sci Fi artifact or event, that’d be a whole other thing, and the process and debate of giving them rights and what to do about it would be complex and an ethical minefield on what to do or don’t do. Probably planet of the apes. But with cats and dogs.
