I have an 8-9 week old kitten who left her mother a week or two ago. I have read on the posts about kittens nursing blankets, wool, other cats, their tails, etc. This kitty does none of those things, but what he does do is suck on me, every time I pick him up, constantly. He sucks anywhere he can touch, my arms, my face, my ears, my legs, anything that's not covered. I can't even pet him because he's doing it completely constantly. I don't think he was weaned too young. He's healthy and he seems happy. I've bought him several soft toys but he doesn't pay much attention to them. What should I do?
