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.
Aww thank you for thinking about him <3 This is extremely valuable advice. I've been wondering how to teach him in that regard. Will definitely try it out!
