Apart from not being puppies, and not being homeless, my cats are very much like homeless puppies. They would be homeless, if I hadn't adopted them. In fact, they would be dead.
I am well aware, believe me, that many human beings are also suffering in the world.
If adopting Petuk and Allie would for some reason prevent you from relieving human suffering, I guess that would be a pretty strong moral argument against adopting them.
Otherwise, that point is irrelevant.
