No, Hudson and Payton, are NOT good options. Or Nikita, for that matter.
The whole point in re-pairing her with a new male should be to do someone who has no ties to the Aussie x Arki lineage. That way, down the road (realistically 1-2 generations from now unless new blood arrives), her hypothetical offspring and grandoffspring could be bred back to her exisiting grandcubs, as that would produce animals with a lower co-efficient of inbreeding, as opposed to if they simply went with another Aussie x Arki male.
