(Btw what I say might now be wrong but it's what I've been told by my friend who is blind)Surprisingly, when you're blind you see like a bunch of colors! Like little specs of color just floating around
Ooo, that sounds really cool! Though, if I'd have to take a guess, I think that Mossy is going off of the blind perspective like Jayfeather where he says that everything is dark which is probably why everything is black when you make your cat blind.
