(Again sorry if you have suggested this ^^) Perhaps we could have some form of ageing to our nichelings when they become elders? I have seen some comments suggesting haveing the fur around the snout and ears lightening, or going completely white. They could also have degrading eyesight or hearing, and their gems could either darken or lighten in contrast when they age.   Baby Light coloured gems and fur colour. Some patterns have not shown up yet. Teen Both gems and
