A cat's normal body temperature ranges from 38 to 39.2°C, a range applicable to cats of all ages. However, kittens typically have slightly higher body temperatures than adult and senior cats. Besides illness, physiological factors such as ambient temperature, the cat's emotional state, and whether it is exercising can also affect body temperature.

In clinical practice, several methods are commonly used to accurately measure a cat's body temperature: ear temperature measurement, rectal temperature measurement, and skin temperature measurement. Each method has its advantages and disadvantages, and the most appropriate method should be chosen based on the specific situation. Measuring body temperature allows for the timely detection of fever or abnormal body temperature in cats, enabling appropriate treatment measures to be taken. Therefore, understanding the normal body temperature range for cats and the correct temperature measurement methods is crucial for pet health management.
