Necropsy on 2 year old Maine Coon stated he died of heart failure caused by elevated Potassium levels caused by a UTI. No indication of a problem from the cat. Fine one day and gone the next. Ever hear of such a thing?
But wouldn't that have been found in the necropsy?Originally Posted by cloud_shade
It sounds like he may have had a blockage--
No matter what elevated the potassium levels, it isn't unusual for heart failure to be the end result if the levels went high enough because severe changes in potassium levels disrupt normal cardiac function (whether it be too much potassium or too little) . It does sound like the kidneys did fail at some point, whether due to infection/obstruction or underlying disease.Hyperkalemia
Hyperkalemia (excess potassium) may result from the inability of the kidneys of end-stage CRF cats to sufficiently rid their bodies of excess potassium. Hyperkalemia can stress the heart and could potentially cause heart failure and/or other associated problems.
