A Trading Plaza is part of the location index. Trades that move pets should finish inside the game's trade window. A promise to pay you back in a later trade, a chat message, or a site outside Roblox is not a trade.
What changes a pet's trade interest
Rarity is only the start. Players ask for pets that are still hard to hatch, still useful on a team, or no longer obtainable. A limited event pet can be more requested than a permanent Secret with a weak card. A permanent Secret with a strong card, such as King Doggy's published +2,750 / x3,300 / x50, is a different object from Timberdoodle's +44 / x2 even though both are Secrets on the same egg.
Shiny, Mythic, and XL are variants. Say which one is in the window. A normal Inferno Dragon is not the Mythic Inferno Dragon from the old 59 Robux Inferno Egg.
Demand moves on Fridays. The game page says updates are every Friday at 2 PM EST. A pet that was hard on Thursday can be in a new egg on Friday. Look at the new egg panel before you give away a limited pet for a permanent one.
A check before you confirm
- Count every pet on both sides of the final window.
- Match the variant: normal, shiny, mythic, or XL.
- Ask whether the pets you receive raise a team you use, or whether you are only collecting.
- Cancel if the other player edits the offer or tells you to hurry.
- Ignore any bonus that is supposed to arrive after the window closes.
This site does not publish a coin price for pets. No stable price list was captured that could be treated as the current market, and Friday eggs move that market. Compare the offers you can actually see.
Duplicates
Keep one equipped copy of a pet you use. Extra copies are the ones to trade, unless a quest or index still needs the duplicate. Do not trade your only farming pet for a Secret whose card is lower than what you already equip.
Scams that do not need a special name
The pattern is the same: the good pet is shown, then the window changes, or the good pet is promised after you confirm a worse window. Stay inside one window and read it twice. Staff will not ask you to trade a pet to a stranger to fix a bug.
