Cat Fever: Symptoms, Causes, and Temperature Thresholds

Section 1: Causes of a Cat's Fever

When a cat feels unwell, its body temperature can become irregular. It's crucial to promptly measure your cat's temperature to determine if it has a fever. A cat's normal body temperature ranges from 38℃ to 39.5℃; interestingly, this is higher than a human's. Typically, a cat's temperature is lower in the morning, higher in the evening, and can rise after exercise. To measure your cat's temperature, use a rectal thermometer. You can also check the temperature under the armpit or at the base of the hind legs.

Should your cat be uncomfortable with the insertion of the thermometer, it may struggle and become restless, which can cause a slight increase in temperature, but usually not more than 1℃.

Section 2: Symptoms of a Cat's Fever

A cat's temperature usually dips in the morning and rises in the evening, with a daily fluctuation of 0.2~0.5℃. External factors like high temperatures, eating, activity, excitement, or stress can cause temporary temperature spikes. However, if your cat has rectal inflammation, diarrhea, a loose anus, or if the rectal thermometer is inserted into the large intestine, the temperature reading may be inaccurate.

Understanding a cat's normal temperature is essential, as most illnesses are accompanied by a fever. Therefore, if you notice anything unusual, the first step should be to take its temperature. A cat's normal body temperature is generally between 38~39℃, and it feels warmer to the touch than a human. The correct method for measuring a cat's temperature is through the rectum. However, if there is a strong aversion, you can also check under the armpit or at the base of the hind legs. To maintain your cat's health, it's important to tailor the approach to its preferences.

When a cat has a high fever, even its usually cold ears and tail may feel warm, and it may become exhausted, lying down on a cold floor. Even without a thermometer, you can tell that your cat is feverish. If you observe any of the following symptoms, seek veterinary care immediately, and hospitalization is recommended if the temperature exceeds 40℃.

Be vigilant about your cat's temperature, as even a slight rise can be a cause for concern.
