''Viverricula indica'' are also carnivores, and they had much spatial and temporal overlap with ''Eupleres goudotii'' when introduced to the same ecosystem the ''Eupleres goudotii'' were in. This overlap has shown to potentially have a negative impact on native carnivore populations such as the ''Eupleres goudotii'' because of the two species competing for similar resources.
