Thanks gornotck for your contribution
Normally I wouldn't reply, as I feel you're being a tad aggressive (or perhaps passionate about coeurls which is really cool by me, they're awesome! So forgive me for assuming you're being rude if that's the case), and I feel that is a tad unwarranted in this circumstance.
Firstly, I enjoy discussing lore aspects here with people whom I would consider my "lore friends," and when errors are picked up amongst us, I notice that people politely report them to SE, most of the time they get rectified, and we have a better game to play because of the care put in. I feel that this could be potentially one of those circumstances, however minor.
I am not arguing with you, and yes, I am aware of the kitten description. I can fully appreciate the growth of "whiskers" coming with time - it was not really what I was highlighting by mentioning it. I feel that there may be some communication and design errors between the creation of the minion and the preexisting lore that predates the implementation of the kitten and its surrounding quests. This can be seen with how originally, coeurl young (the pups) are being treated like the young of leopards - born without spots - and developing these spots as they grow older. (Also, it wouldn't be the first time there have been some communication/design errors within the game, such as with the Rothlyt Sound being used in many item descriptions, including leves, for events and enemies around Aleport and Vylbrand, even though it is on the opposite side of Aldenard and nowhere near La Noscea. The leves were rectified, but the enemy names remain...)
As an aside, I also feel that the minion may have just been given this coeurl lore to "fit it into the world of ffxiv" - in Valentine's day promotional art, and in the .dat files, there is a very similar minion/cat to the coeurl kitten, but coloured all black. Perhaps these minions were simply designed on domestic cats? Perhaps they were based on coeurls and jaguars, and the designers did not fully consider the full spectrum of the coeurl lore? Maybe I'm just overthinking it all? Perhaps, like I have previously suggested, the sequence of growth is correct, and the kitten just simply has a spotty, darker baby coat that moults once it gets whiskers?
Either way, I apologise if my thinking aloud makes you angry. It just does not seem logical or sequential to me, and I like to hear other's opinions.
