Dear Carla: Thanks for bringing this to light. Goes to show that you can't believe everything that you read. >1. "As I mentioned, ferrets are extremely susceptible to colds and >flu; they usually die if they contract measles." Flu yes, colds (generally caused by rhinoviruses), no; and measles (as a spontaneous disease) definitely not. Now, measles is caused by a morbillivirus, the same family of virus that causes canine distemper (perhaps this is where the confusion began.) Ferrets can be infected with the measles virus in the laboratory via inoculation; however, there are no reports of ferrets spontaneously contracting measles from humans or other ferrets. >2. "I recommend a glass [water] bottle, at least if you live in an >area with hard water. Why? I'll tell you my story. For many years, I >lived where we had fairly soft water.

This is an interesting observation, however, there is no proof that soft or hard water, or plastic causes adrenal tumors in ferrets. I would submit that there are probably as many cases of adrenal disease in ferrets in locales with hard water as with soft. I can attest to a number of my ferrets having adrenal disease - while our water is fairly hard, all these ferrets have drunk from ceramic bowls. It is one thing to make such claims, and we hear them all the time. However, it is a different subject altogether to make such unreferenced claims in a nationally published magazine which many naive ferret owners would use as expert opinion on the care of ferrets. Amused, and with kindest regards, Bruce Williams, DVM [Posted in FML issue 3255]
