When a cat has repeated fevers, it may be caused by viral infection, injury, peritonitis and other diseases. You can first observe whether there is any trauma on the cat's body. If there are obvious wounds, you can use iodophor for local disinfection first, and then take the cat away. The pet hospital will conduct an examination to confirm the cause of the disease. During this period, attention will be paid to increasing nutrition for the cat to promote physical recovery.
