Why is it biologically incorrect that the meerkats in a well known advert have Russian accents?

The Meerkats in the advert have Russian accents, which is biologically incorrect because accents are a human construct tied to language and culture, not applicable to animals like meerkats. Meerkats are native to southern Africa and do not have any form of communication that resembles human language or accents. Their vocalizations are instinctive and species-specific, making the portrayal of them speaking with a Russian accent an anthropomorphism that misrepresents their natural behavior and Biology.
