Feline Fever of Unknown Origin
Determining the cause of elevated temperatures in cats can sometimes be challenging, but a thorough medical history can ofte provide clues.
Simply put, fever is a term that refers to an elevated body temperature. In cats — as well as in humans — the hypothalamus is a structure in the brain that controls the “thermal set point” for the body, in a fashion very similar to a thermostat. When body temperature changes, the hypothalamus responds by making appropriate adjustments so that more heat is produced if the body temperature is too low (for example, by shivering) or heat is dissipated if body temperature becomes too high (for example, by sweating and panting). This effectively keeps the central temperature at near normal levels.
