Get chuuro kitten, see if they’ll have that. You can use the syringe they gave you for Albon/dewormer to pipe the some water or water + wet food slurry into kittens mouth who isn’t eating. Watch for lethargy, jaundice, tacky white gums. Try to make sure kitten has something/water at least. And seeing a kitten pee is more important than it pooing. How old are ur kittens?
