I'm really really sorry if this have been suggested before, I looked everywhere but couldn't see that it had.
Please lock/delete if it has.
I was wondering if there could be a little " You already own this pet" like the "This pet is in your wishlist" under the pets when you trade.
Maybe it's just me but i've accpeted a trade only to find that I have one of the pets already. XD
I am quite forgetful though.
