Final Fantasy 14 – Understanding Loot Lockout for Binding Coil of Bahamut

Although there are a few kittens in the game -- the Cait Sith Doll minion, for example, as well as a significant portion of the playerbase -- they can all rest easy for now, because the Goobbue Sproutling doesn't appear to have any special behavior around kittens, barring any exceptionally well-hidden easter eggs. While a similar description also appears in the German flavor text, the game's other two languages don't make any mention of kittens at all.

If you're curious, the French flavor text roughly reads "be careful not to get your fingers bitten," and the Japanese is something along the lines of "word is that the cost of feeding him is nothing to sneeze at."

Being able to give gil to your retainer is likely just a holdover from version 1.0 of the game, where retainers would more directly carry out buying and selling items in the markets on your behalf, so there was actually a purpose to giving them money. For example, you could set up your retainer with a stash of money and a "buy" order, so that other players could choose to sell items to your retainer for an offer price that you set up ahead of time. Likewise, for a period of time you could put your gear up for repair with your retainer, along with a gil reward for any players that repaired that gear.

Although it currently serves no necessary purpose right now, some players like to use their retainers as a piggy bank; a place to squirrel away money so they can't impulse-buy things from the market wards as easily. :)
