Although lasix may be lethal to a ferret, it will help congestive heart disease (cardiomyopathy) if administered properly and the ferret's hydration is monitored. Our Abby was diagnosed with cardiomyopathy nearly 4 years ago. She was treated with lasix on a daily basis, then weaned over to a Duck Soup recipe containing vitamins C, E, CoQ-10 and alpha Lipoic acid. She still gets the lasix every so often (maybe once a month) when she begins coughing. She's over 8 years old now and still active. Your vet should be able to prescribe 1-4 mg/kg of lasix once a day, according to Hillyer, et. al. "Ferrets Rabbits and Rodents, Clinical Medicine and Surgery." Maybe you should buy your vet a copy for reference. I believe Amazon.com carries it. Dick B. - not a vet. [Posted in FML issue 2306]
