When Zeus was diagnosed with Pancreatitis, he was throwing up yellowish liquid. I would take her into the vet to be on the safe side. Pancreatitis is common in these little ones and can be very serious if not treated. I am sure it is nothing, but you can never be too safe. My vet told us to give Zeus 1/2 a Pepcid AC twice a day. Try this in the mean time. Hope she gets better soon!
