There is now an extra piece of information on your pet pages: The pet's rarity. It gives you a basic idea of how rare your pet is. We're still tuning this a little bit, so don't be surprised if your pet's rarity changes over time .
We plan to show this information while you're trading, so that you can see at a glance if your offer is reasonable or not. Hopefully this will stop people from asking for a whole bunch of rare pets for practically nothing in return.. . Probably we will allow you to automatically block trades which are too unfair.
