Even Healthy Cats Act Sick When Their Routine Is Disrupted

ScienceDaily (Jan. 4, 2011) — A cat regularly vomiting hairballs or refusing to eat probably isn't being finicky or otherwise "cat-like," despite what conventional wisdom might say. There is a good chance that the cat is acting sick because of the stress caused by changes in its environment, new research suggests.

Healthy cats were just as likely as chronically ill cats to refuse food, vomit frequently and leave waste outside their litter box in response to changes in their routine, according to the Ohio State University study. Veterinary clinicians refer to these acts as sickness behaviors.
