So, what do you people do with multiple versions of the same pet?
I understand there's no real reason to keep them, but I cannot always bring myself to not catching a Rare if I have the chance... I still hope Blizzard will eventually allow us to cage them and sell them on the AH, maybe with some restrictions like raising it 10 levels or keeping him at least 90 days or so (to prevent farming). Not because I desperately want to make money but more that it seems like a waste to not save a Rare pet.
Another matter are the multiple pre-Pandaria pets. I have quite a lot of those, because I was collecting on all of my alts. So I have a lot of especially the commonly available pets. I like to keep the unique feature of having 8 or 9 similar pets. but again I know it's not of any use. And I probably need the slots anyway, because there is a max of 500 pets (allegedly 650 after patch 5.1)
Speaking of which: I usually cannot catch a new pet if I own 499 - I would assume there is still room for just 1, but apparently not so. But abut three days ago or so, I all of a sudden had 510 pets?? No idea whether I just kept on catching, or that the counter was bugged. I have been cleaning up and now own like 487 or so.
