That's because they are large stuffed doll/plushies, no matter how lifelike they look! I mean it's the same thing as real life, there are some very lifelike looking dolls (I'm looking at one of my giraffe dolls right now) but it's clearly still a doll.
The reason we don't have plushie in the name of wearable dolls/things like it is because having 'plushie' makes the database think it's a plushie and will try to add it to collections, which is a thing we don't want in the case of these dolls haha.
We've had other wearable dolls that have very obvious stitch marks to show hey, this is a plush nOT AN ACTUAL PERSON YOU'RE HOLDING OR SPECIES. (example: the rag dolls from Morostide)
I think this is really a preference thing. I like the stray hairs! I think I started the trend, actually, back during the Saheric Temple plot with the little stone guardian plushies. Oops. (PEOPLE LIKED THEM!) I don't think the little hairs say second hand! Some of my favourite plushie makers irl make 'tatty' bears, they're absolutely lovely.
It became a stylistic thing with the lifelike dolls too. The thing is with those, is that most of the species are actually done and have been for a long time, but we're releasing them with the pet articles rather than flooding the market with them all in one go. (This also really helps us keep track of them)
So the neela is a lot newer than the feli, and we've sort of finelined the design of them by this point. We have in our more recent lifelike dolls made the little hairs and such more subtle. But there's a backlog still to come out of the older ones, and I'd not want to just change the style of the dolls at this point anyway!
