Little Pod s dreaming , as he is learning more and more about the World around him.
And Sweetpea may be overly attentive to her baby, but shes a very young Momma Cat, and may not be sure what to do.
But if Pea Pod is growing , she must be doing something right.
I would try a bag of Royal Canin Baby Kitten Food, usually 1.99 a bag, in a week or so.
