Our new kitten is hiding away as to be expected. I've put food and water there and easy access to the litter tray so she's got everything she needs in easy reach. However she is crying constantly and I don't know what to do, it's a really loud distressed cry and so sad to hear. We've left her alone to hide and not tried to coax her out etc. as that's what's always worked previously but I don't want to leave her crying like this. She's been doing it for hours.
