Now i dont know if you can do it with the 10k*s and up but i know u can do it with 500* pets.
What you do is Make a mannequin, if it doesnt make u autobp then bp it. then trade the pets u want to trade to someone to it.
then have them make a mannequin of the opposite sex marry it and trade the pets to the newfound spouse. then just tell them to trade it to their main. its so much easier this way and you dont have to bug king.
Tell me your results on pets over 500*.
