A cat's normal body temperature range is typically between 38.5 and 39.5 degrees Celsius. This range applies to most adult cats; however, kittens' temperatures may be slightly higher, generally between 38.5 and 39 degrees Celsius.

Of course, a cat's body temperature is affected by many factors, including the ambient temperature, activity level, and emotional state. These factors can all cause fluctuations in a cat's body temperature within the normal range. If pet owners want to obtain the most accurate temperature reading for their cat, it's best to use a rectal thermometer, as this is the method that most closely approximates a cat's normal body temperature.
