Just a friendly reminder that faction pets will show up in your journal and as collected since the latest patch.
So be sure to make an opposite-factioned toon and do the quest for the Horde/Alliance Balloon and the Argent Gruntling/Squire.
Also, at the moment, the opposite factions guild page and guild squire do not show up as collected in the journal if you have them, but will show up as collected if you log on the opposite faction.
Furthermore, the opposite faction's Moonkin Hatchling shows up as collected.
Happy collecting in MoP!
