It costs me hours atm to figure out which of the pets that I got in the birthday event I already have. 3 were on my wishlist, so no problem with those, and of course there are some that I remember having, but still a huge horde is left where I have to check the info what year they are from, then go to the previous released series guide, search for that creature, find out about the releasing month, go to the clan of mine that contains that month and check if I have the pet or not
Perhaps there could be added an info about how many of that pet I own, so if it says "2" I immediately know that I already have it. The normal "you already own it" - info does not help here, because it doesn't tell if I own it for the first time or have several of it.
