Cats showing signs of fever for more than 24 hours or a fever above 106ยบ F at any time should consult their veterinarian. The veterinarian can perform tests to determine the source of the fever and take steps to treat the underlying problem. If a bacterial infection is a source, for example, antibiotics may be needed. Moderate or severe dehydration is treated by administering intravenous or subcutaneous fluids. Never give your cat medication without the advice of your veterinarian. Certain fever medications, such as acetaminophen, are toxic to cats. To learn more, visit our website, https://www.mvet.ch/tpost/e6ruemjdk1-fevers-in-cats
