I recently found a kitten uder my porch a d I took him In but it been a while ang he is still so thin. He so bony he has a bony face and bony legs but eats like a horse
oh friend, he might have parasites! my Pangur had giardia when I first got her, and until we rid her of that she was just a bundle of twigs
bless you for taking him in - I hope you figure out what’s keeping the weight off!
