I'm also a vegan, but it doesn't seem likely to me that other species have languages similar to ours. I think people have already used ML to interpret cat and dog communications, and they got general emotions more than something like syntax.

It's complicated by the fact that other species' throats and mouths physically can't form many human language phonemes*, but even the use or recognition of human language by other great apes (and parrots) is very controversial, and they probably have cognition and sociality most similar to ours. But it's not clear that they can do much of what human language does.
