I would assume a more challenging environment
I think perhaps we assume a different time scale. In my example I posited one or two rat species surviving and thriving, but it would more likely be 50 species and a few mole like animals, and some we can't describe in current terms. In a few decades time most of these would succomb to the devastation and disease and lack of partners.

On a longer scale of time of a few hundred years to a few thousand it is as if all died but the one or two I imagined. I just skipped the step of those who survived, but not for long. I also didn't mention the transitional species. These are the ones who adapted to a niche but not all that well and were out competed by decendants who adapted better. These include the dog-like creatures, some of whose decendants became dogs, some became seals, but the ones who just remained dog-like all died out.
