I read this post: http://royals.ms/forum/threads/evolving-pets-clarification.11300/#post-58264 And I'm just wondering, can you level up the pet to 15 through the pet park JQ? I'd rather not spend 17k nx on pet food if I could avoid it, thanks!
Don't buy pet food from cash shop, and I wouldn't bother too much with leveling your pet at all as there are issues with pets saving information, the pet food will be used but likely not save its new level. In the new source it will work like in GMS so better wait for that.
