I rescued this little guy around 3 weeks ago. I never took care of a kitten before, but fortunately he's been making amazing progress. He's almost fully weaned at this point.
Shoutout to user Joshua Nozzi from my previous post, who urged me to see a vet. If I went any later he may wouldn't have made it.
I find if you "overreact" a little when they bite a bit too hard, they usually get the hint pretty quick. Beezly the kitten has pretty much figured it out now, although she still thinks climbing my leg as if it's a tree trunk is the greatest thing ever, especially when I'm trying to get her food ready. She tends to forget manners when she get excited in the least bit.
