Thank you, Quintessence. I now understand why we get 3.

Okay, now that I've logged in each character, I have 7 Wolpertingers (and many other duplicates). I understand with MoP, it will get reduced to 3 of each. *Why* do I want/need 3 of any pet? Do pets get stolen? Do they die and never come back? Am I supposed to do something with my 4 extra Wolpertinge...
