Measure the body temperature. Generally, the body temperature of a healthy cat is 38~39.2°C, 39.2°C~39.5°C is a low fever, and above 40°C is a high fever. Touch the cat's ears. If the ears are very hot and the exhaled air is also relatively hot, it means that the cat's body temperature is very high. Touch your cat's belly and four pads. If it feels hotter than usual, your cat may have a fever. ​​​​​​

You can also pay attention to the cat’s appetite. If the cat has a fever, its appetite will be greatly reduced. You can also tell by checking the cat's fur and paws. If the cat has a fever, the cat's fur will appear very dry. Generally speaking, the most reliable method is to measure the cat's temperature, but when measuring the cat's temperature, you should pay attention to the following rules: When the indoor temperature is too high in summer, the cat's body temperature will be no more than 1°C higher than usual. The body temperature should be slightly higher at night and slightly lower in the morning. The body temperature of adult cats is lower than that of kittens. When cats exercise or are nervous, their body temperature will temporarily rise.
