When I go to my pet page it says 34/34 That's the only thing it will show. My friends used my iPad and was able to see their pet stats.

It might have something to do with special characters in Minion names as far as I know. Can't say who found out, but I remember reading this on another Topic about this issue. :)

Just see which Pets have special character Minion names and use this link to change them. :) http://subeta.net/pet.php?act=minion&petid=PETID

I hope this is your issue :)

Thank you @ gore
