i know dawn has a safe ph level, can also be used as a shampoo if needs called for it
tk it also sounds like this kitten is going through a seperation thingy u might want to try that tick tick idea and maybe a small stuffed animal, i dont know make it a small area of blankets so it can tunnel into ,see if that helps lower the MEOWS , worse case find one of its bros or sis and take it in too

pretty sure after that last advice my help is no longer needed lol
