Do you get German translations for the meows?

I got it on Firefox for android. Maybe locale matter as someone suggested.
I didn't see it and mine is in French, I do see it with "Chat" and "Katze". If I search "Cat" the spot is taken by the company, not the animal, could it be something similar for you? I feel like that's the actual issue.
