oh shit, we in the baltics have something similar, but in december 24th. it is said that barn animals are able to speak, but it is forbidden to listen to them, because listener will lose ability to speak. i think it is possible that baltic pagans also listened to animals, but with christianization they were fear mongered not to do so anymore.

I am western slav and we have the same legend about talking animals on christmas. I heard one story especially mentioning talking cats but my memory of it is verry blury and I do not remember literally any details
