im trying to auction my pet, nero, but everything is just gray? im pretty sure i was able to auction him earlier today, but like i said, everything is just gray.

is this because i have bid on an auction, or because i have other pets that are pregnant?

Is he currently busy  (fighting on arena, exploring an island, training, doing a quest, offering a breeding)? If so, finish or cancel whatever he's doing.

no, hes not doing anything
