With an older cat that has a decreased appetite I would make sure to check two areas: 1) The mouth- periodontal disease makes it painful for pets to eat. Resolution involves doing a thorough dental cleaning and any teeth extractions, if indicated. 2) Intestinal lymphoma- makes pets nauseous and won't show up on routine bloodwork. Abdominal ultrasound often is needed to diagnose. Pets can go on medication to slow progression and also increase appetite if this is the case. It would also help to discuss specifically her bloodwork results because even normal values are helpful. And high albumin protein usually just indicates dehydration; however high globulin protein can mean other more serious disease processes. I hope this helps and I hope Tsunami feels better soon!
