Dear Shirley >I have a friend whose 4 year old ster. male ferret, Herbie-Heartbeat, has >had 2 minor strokes a matter of days apart. He recovered from the first >one with no lasting symptoms but is only slowly recovering from the second. >His vet has prescribed aspirin (sorry, can't recall the dosage), each day >to prevent further blood clots forming. Does anybody on the list have >experience with this that I may share with the distraught owner.... eg >prognosis, holistic care, hope? Unfortunately, I have no experience with strokes in ferrets, nor do I think they have ever been documented in ferrets. In fact, I would tend to think that this is a misleading diagnosis which was probably not backed up by any definitive lab findings. Let me tell you why I am a "doubting Thomas" on this one. Many private practitioners tend to ascribe human diseases such as heart attacks and strokes to their patients as their owners tend to understand these diseases and the poor prognosis associated with them. Why don't ferrets have strokes and heart attacks? Because they generally don't have the causal diseases of hypertension and atherosclerosis. Ferrets don't get hardening of the arteries, they don't need bypasses, and they don't get myocardial infarcts (at least I've never seen one. The primary reason that they don't get atherosclerosis is that their diets are much better than ours - less saturated fats, less processed sugar, less sodium! We also don't see hypertension in ferrets, and that, and atherosclerosis, are the two main risk factors for strokes, at least in humans. I've looked at lots of ferret brains from animals with neurologic deficits, and never once seen any evidence of a stroke (which essentially results from rupture of a cerebral vessels and hemorrhage into the surrounding brain). Weakness in the hindlegs, be it either unilateral or bilateral, is not an uncommon finding in ferrets, and without resorting to an autopsy, can be very difficult to diagnose. But if you get a diagnosis of a stroke from your vet, ask how that diagnosis was obtained - MRI? cat scan? skull X-ray? spinal tap? or just classic clinical signs and experience? I'd like to know!
