I sure hope sickly darling kitten is hanging in there. I had a kitten once who hadn't been weened. She would not drink so I got a bowl and put her down beside me and showed her how. I licked from the bowl off and on for two days right beside her.... I wasn't thinking it would work...she finally started drinking thank God. After that she was fine. Try putting extra calories into everything if you can. If kitty ain't eating, she sure as hell won't poop. Best of luck 💕❤️💕
