Bought Kitao at pet auction with around 430+ gym and 180+ elites
in the fall of 2016 for 70 or 75mil(can't remember).
Been holding onto him and statting ever since.
Edit: almost 6 years later, Pet auctions are no longer a thing.
I have just about tripled all of the stats on this pet . He is never for trade, unless there are higher stats on the line.
