https://www.vetsurgeon.org/f/clinical-questions/30087/cat-with-peritonitis I saw a cat last Friday with peritonitis, sadly it was euthanased without a definite diagnosis, but I wondered how other people would have approached the case and what conclusions they would have drawn from the results. 2y6mo F(N) DSH.

Pancreatitis was in my mind as another possible diagnosis, but I would have expected a higher cell count in the ascitic fluid.</p></p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/234253?ContentTypeID=1Wed, 08 Dec 2021 10:00:52 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:e9edf098-980d-4443-b3b4-2eb96e6e043bLucy Fleming<p>[quote userid="6297" url="~/001/veterinary-clinical/small-animal/medicine/f/discussions/30087/cat-with-peritonitis"]globulins were normal.[/quote] <p>Can you remember the a/g ratio?
