I am sorry Pippi is not feeling well. I know sometimes Buster refuses food and it freaks me out because he always eats. She may just be feeling a little out of sorts. Check her gums and see what color they are as you want to make sure she does not have hypoglycemia. Here are some threads discussing hypoglycemia. Do you have Nutrical on hand or perhaps Kayro syrup? Give a little followed by some protein. I do know people warn against giving them honey. Sending prayers and best wishes that Pippi is just feeling off and there is nothing wrong.
