American Heartworm Society Announces Updated Feline Guidelines

A rigorous review of the latest data on prevention, testing and treatment for feline heartworm disease has led the America Heartworm Society (AHS) to update their Feline Heartworm Guidelines. Development of the updated guidance, which available on the AHS website at heartwormsociety.org, was driven by the need to address persistent underdiagnosis and undermanagement of heartworm disease in cats and was completed after a thorough scientific review by experts from the fields of parasitology, cardiology, and clinical practice. Veterinarians who rely on this vital resource will find revised recommendations for heartworm screening, mosquito control and treatment options for heartworm-positive cats.
