Beast-kin

There are a number of beast-kin, but all seem to share the following trait.
Tribal Bond: Beast-kin tend to form close bonds with their community as they see them as their tribe and will adopt many of their customs. This community can be the local community, an organization they are a part of, or other such group. This bond is as much instinctual as it is learned. So long as the "tribe" continues to treat the beast-kin well the bond tends to remain through generations.
Note: Other "beast" races such as Tabaxi which are in 5th ed D&D lore are in the world as they are written stats and abilities wise just not lore wise. Just add in the above tribal bond and know that they are classed as Beast-kin for spells, abilities, feats, and such.
