What ursine animals come in sleuths of boars and cub-bearing sows?

This is a bit of a trick question! The terms "sleuths of boars" and "cub-bearing sows" are not standard terms used to describe ursine animals.

Here's why:

* Ursine animals refers to members of the bear family (Ursidae). While boars are members of the pig family (Suidae), and sows are female pigs, these terms don't apply to bears.

* Bears don't have specific terms for their groups like wolves (pack) or lions (pride). They might be referred to as a "group" or "cluster" of bears.

Therefore, there is no ursine animal that fits the description you provided.
