Many people have asked for animals that are common but special to them, or possibly rare and exotic in their part of the world. Real zoos do have some of these critters (I checked--the San Diego zoo even has a raccoon exhibit). Maybe one "backyard" critter for each continent, except Antarctica? These are critters that might not end up in a pack otherwise.
Red fox--Europe (we have a number of subspecies in North America too, though)
Raccoon--North America
Not so sure which species are super common "backyard critters" in other places, though. Maybe a mongoose for Asia? What critters are common "backyard" beasties in Australia, South America, and Africa?
Also assuming we don't get aviary animals in the game, which could change the nature of future animal packs so they aren't mostly mammals.
