this is my pet, there are many like it but this one is mine.. I think he means sorc pets, which level up as you use them (ala the sorc minion summoning skill appropriate for that pet).
Yes, just for fun. Vanity pets are special in-game items either purchased or earned (like from participating in a beta stress test). They do not influence the game; they just follow you around, look cute, and make noise.
A note for those who Sneak. Your pet does not sneak. In beta more than a few players in PVP were "caught" while Sneaking because of the pet following them around.
Not sure if this is still true now that the game is Live, but keep it in mind.
