Feline distemper, also known as feline distemper, feline panleukopenia, and feline infectious enteritis, is mainly a highly contagious infectious disease of young cats. The disease widely exists in the United Kingdom, the United States, Germany, Hungary, France, Japan and other countries. It has spread to most areas in my country and has become one of the major cat diseases. ​​​​​​

The characteristic symptoms of the disease are vomiting, fatigue, and an increase in body temperature above 40°C, which lasts for about 24 hours and then drops to normal temperature, but the body temperature rises again after 36 to 48 hours (multiphase fever type). The sick cat had diarrhea, watery feces with blood, severe dehydration, and rapid weight loss. At this time, the sick cat was depressed, its coat was rough and messy, and it was indifferent to the owner's call and the surrounding environment. Sick cats usually die soon after the second temperature peak, or they may recover after the second temperature subsides.

There is currently no effective drug for this disease at home and abroad. To prevent secondary infection and dehydration, broad-spectrum antibiotics can be added to the infusion. Vaccination is the best way to prevent the disease. At present, inactivated vaccines and live attenuated vaccines have been widely used abroad, and the results are very good.
