Presapient yinrih would cache food in communal larders shared by single families and sometimes entire shires depending on local culture. Communal food caching is very rare on Earth (only two species are known to do it according to Wikipedia).
This mostly consisted of dry seeds and nuts gathered by female pups too young yet to accompany their dams on foraging trips. Male pups would practice “hunting” small invertebrates and occasionally add their kills to their sisters' bounty. Sometimes these seed caches would sprout before being eaten, laying a foundation that would blossom into true agriculture when the yinrih achieved sapience.
