Lizzy, Tess was on fluids only (intravenous) for 2 days then commenced on hills id canned food on the third day ( small amounts often) . She stayed on small amounts often for 1 week then twice daily feeds from then on. She did really well with this regime. It is also how they treat pancreatitis in humans (intravenous fluids only until pain and vomiting settle then small amounts of oral fluids then progress to foods). Hope this helps good luck :p
