X of 624 pets wanted

[Jyru]

So I was a little confused and thought someone could point out what's obvious,
but my COLLECTION says 374 of 624 pets and my wanted says 334 of 624.

374 + 334 is 708 which is a little close to what I had heard the total number of pets is.

So i'm curious why they are 'of 624'

Your current number of total pets wanted (624) doesn't take into account pets that can't be obtained yet. There are 84 pets that won't be available until WoD is released.

334 Wanted - 84 Unreleased pets = 250 Wanted
374 Unique collected + 250 Wanted = 624 Total

Hopefully this clears things up
