The following are the translations into Russian (not Belarussian) for the animals/furs of which you speak. The two languages are fairly closely related, and something quite similar to the Russian words may be the accurate Belarussian.
Thanks for the help Polycarp, I tried russian first ( thats what language I assumed it was in ) and none of the russian words seem to fit. I guess I’m gonna need a fluent Belarusian…
