Just fyi on the cats, you can customize them later in game at various npcs. Each npc has its own set of "Customization". Face, fur, body etc.
I've seen some funny ones, with super small Lynn(they get pretty tiny if using minimum height/build) and then the largest cat body they could(some say it helps with targetting in pvp as people will target the cat).
If I go my Calvin and Hobbes theme(if I play summoner, till a toss up between it or assassin), I was going to do a small body(calvin) and then a big cat(to mimic Hobbes as Calvin "Sees" him).
