Any insight on my cats weird habit?

Ello. This is just something I’ve been wondering about for a while. My cat is a real licker. I have heard that kittens seperated from their mothers too soon will develop this habit. Is that true?

Furthermore, not only does he aggressively try to clean me (he also really likes to lick hair) but he will often be licking me and then bite me in the same spot! (This is funny because he has no teeth so it feels so weird) And he’ll “bite” a few times, like he’s nibbling on me. He does this mostly to my nose but has also done it to my arm and leg and just now my hand. I just wonder what the hell he’s doing. Does anyone elses cat do this and why?

Oh and I just looked over at him and he’s eating dust and hair off my rug. Weirdo.
