NEW FEATURE
We have just released Pet Auctions as a new feature to the site. You can use it to sell any of your pets for MP or to bid for any other pets that are up for Auction. This is the ONLY way that you are able to sell your pet. If you want to send someone a pet, use the Pet Exchange and if you want to trade your pet for another pet, continue to use the Pet Trades.

ANYONE FOUND TRYING TO SELL THEIR PET BY ANY MEANS OTHER THAN PET AUCTIONS WILL HAVE THE PET CONFISCATED AND THEIR ACCOUNT MAY BE FINED OR FROZEN.

IMPORTANT - pet auctions work exactly the same as item auctions. Once you have listed your pet for auction, the highest bidder will become the new owner of your pet for the price that they bid. The buyer will also be charged pet trading fees, which you as a seller will not receive.
