Young kittens are
like baby humans, in a way. Their days consist of eating, sleeping and
emptying their bowels and bladders. After the kittens have gotten enough to
eat and have had their bodily functions taken care of, when you put them back
in the "nest," they will sleep or rest quietly until you are ready
to feed them again. If they are restless and crying and meowing, they might
need a little more to eat, or they might have to empty their bladders or move
their bowels, or they might feel cold.
