You need to read more on this subject, because if you were fully informed or you wouldn't have that scepticism. That's not a slam, I'm just saying you honestly don't have all the info or you wouldn't be skeptical.
A national Vet chain (Banfield Pet Hospitals) has reported that there is a SPIKE in cases of acute renal failure (ARF), estimated to be "hundreds per week" during the recall period, that is OVER AND ABOVE the NORMAL number of cases of ARF for the same time period in previous years.
Additionally, ARF is not the same thing as chronic renal failure, which is what your post (rightfully) refers to: "dying of renal failure on a daily basis, mostly due to old age, diabetes"... those are chronic (slow or long-term) kidney failures... "and antifreeze" - that is ARF which comes on suddenly and is due to poison.
(I'm posting a day late, so perhaps you have heard more info by now and are no longer skeptical... if so, disregard this post. :-)
OK, what is the toxicant causing the ARF? With 60 million dogs and a similar number of cats, the "spike data" should be substantial. Show me the numbers please. To date, the toxicants reported do not cause ARF.
