Do you need 3 diffrent types of animal to get to expert rank?

Yeah, for the adventurer rank, you'll need 3 different animals to lvl 70 (example: Wolf, lynx, cheetah). If that's the last thing you need to complete for the adventurer rank to get to the expert rank, then good luck! Hope this can help you, have a good day, and stay safe from COVID-19 ;3.
