It's kind of annoying, but the flip side is it allows people to have one but still get another to sell so someone else can get it. Those without the proper classes on retainers, for example, wouldn't be able to get the fat cat any other way.
They'd have to come up with a new item tag to prevent this
That should be what the unique and untradeable tags do, but by using a specific mount/minion ability granting item you no longer have the item making it so that you can claim another.
