Appetite changes in cats: a note for your veterinarian
Do not dismiss a change as fussiness. Compare the usual meal with what you observed. This is a consultation aid, not instructions for feeding an unwell cat.

Contact your veterinarian when you notice no eating
Appetite loss is a sign, not a diagnosis. Contact your veterinarian immediately when your cat is not eating. Sudden appetite increases also merit discussion.
Food disappearing does not prove this cat ate it. Write what was offered and left. If unsure, say ‘left more than usual’ or ‘did not see eating’ rather than inventing a quantity.

Describe behavior without assigning a cause
Record what you saw at the bowl. Date changes to food or the home. Events happening together do not establish a cause; describe both to the hospital.
When the change began and what eating looked like

Share the same agreed plan
Keep observations, the hospital’s explanation and next actions separate when sharing with family. Confirm food or medication changes with the veterinarian rather than choosing from an online article.
